00:00 oceans rising and falling because of Standing changes of sea level for populous
00:07 falling as a results of seasonal changes rainfall. And that leads the idea
00:13 physical processes that drive sedimentation and erosion independent scale, which they What's more
00:22 is Henry took a photograph of that and the paper that's been quoted a
00:27 100 times. What I'm gonna talk . How that judge a lot of
00:33 on the basis of your citation index your guy. You know, that
00:38 take a picture puzzle on a field , writing paper against 400 times what
00:45 shows with this diagram Is that the you've got a flat area that it's
00:51 than flattened at that point, positive choke points based on those drops
01:10 and there's a new Nick Point There's even the terrorist has come by
01:16 in that little bubble, so that off this of this puddle, Phil
01:24 the kinds of geometries, the kind emotional surfaces, as well as a
01:29 where erosion occurs versus sedimentation. That's consequence of big points chokepoints based
01:36 which is kind of the point of much, and it was also flying
01:42 and out of Salt Lake City in that we all used to go because
01:46 the amazing crops there. Coarse Salt . It is a small that figure
01:55 it was factor in the ice, so the lake level used to be
02:01 here that dropped that it dropped So here you can see a flat
02:07 with decision because of the mid point a result of falling of that,
02:13 thought level that shrunk to become great . And you could see that the
02:19 occurs and the rivers cuts deeply into Point. The worse it gets
02:22 less less. You see, there the go back to my laser
02:30 You can see the shadow that shows steep really here to get shallower and
02:36 and shallower. Eventually, the river of pops out. Starts toe almost
02:40 to oppose it of the at the of that last. So he's just
02:45 400 saying this fears nick points scale nick points of scale of a big
02:52 . Of course, point is, can also make a point scale of
02:57 margins. Photography which becomes important, large systems like stuff some fans in
03:05 Gulf of Mexico. Is that true faulting as well? Vaulting is
03:13 Creative points. Yes, absolutely. is basically falls point trying to
03:27 I thought that point was simply reflect area. Although I'm not talking about
03:32 , the judges think about false, segments, so that point only where
03:42 fault is that phone before, it's very okay. The stock was written
03:54 my buddy John Holbert. It was fluid, your settlement ologists just to
04:01 this time around. So the idea that there's a river, and that's
04:04 black black lines, Jones said. riddled will be graded to some point
04:13 downstream points, and he calls the of downstream point stops. Typically,
04:20 would be the shoreline damn on so points that Burger is is is rated
04:34 dash with 44 stops. He calls the money says that any given
04:43 you will be degrading according to a of things. Lower point rich,
04:59 , the lowest limit that river can IHS party. That's that for that
05:11 line there, so lower point that great too, which is Geum or
05:21 in terms of reviews. His constant controlled by these factors that he called
05:29 he called that started to surface great service towards which the river had admitted
05:42 at its proper profile. So the of this paper was buffers,
05:47 buttresses is point dentistry point for the . The buffer zone is a zone
05:56 within reach. The river grated What this when he calls the lowest point
06:05 the and regret it a way to front. Pfizer, The Landis is
06:13 off. Then the river will keep down as long as the land is
06:18 off with river will come down and the river. If the Landis is
06:23 off recipe, the result comes So someone give me an example of
06:30 area that's been uplifted so much it's of the 10. Exactly. The
06:41 Plateau was lifted up by forces. has come down, down,
06:47 producing a one home. Okay, the lowest medal, too, is
06:55 for by the rate of the right? Right. So the other
07:05 that controls whether in all of rivers greater degrade just like that's coming into
07:14 system. Okay? There is no coming into the system. You got
07:19 license? One of my What's What does that one with that one
07:26 to have way to think about? river is home. So water.
07:33 river that doesn't have a settlement in is hungry. And hungry River does
07:40 of the landscape. So it so sediment influxes low river sentiments Oh,
07:55 eroding. It's a landscape. I like to have that. I would
08:00 to have that material and rode the and settlement. Okay. Felt
08:09 Of course. The scent of influx transform. If Riverhead a lot of
08:23 is through the activity of Okay, home from work. You don't Whatever
08:32 come home from work Making the thirsty beer. Maybe just 1 ft,
08:38 the way, your first. So have some point to get too much
08:46 Foods rich with fear. Get I drink another coat asking you have
08:53 much. You totally floated off on drunk. Too much fear after
09:00 Kerry. Any more beer? What to drink? More drink than you
09:10 Something very pleasant exactly so you could longer you don't have the capacity Harry
09:24 in front and its role in the in this Senate frustrating. But it
09:29 can't carry but raising more but can your sentiment. It will begin to
09:38 . So when it transformed passions I can no longer transform anymore sentiments
09:44 it will begin to it no 17 influx of cash settlement. That's
09:56 threat. Okay, your rate is . Maximum anymore. They no longer
10:05 down. So so that so. things that control the radicals, this
10:15 upper and lower surface to which you , Of course. What control thes
10:24 to this one go home preservation space allows the commission we could start brought
10:38 about the controls on seven notation. if rigorous plates to downstream, whether
10:45 all sedimentation, occurs there for primarily five static on that sort of one
10:52 the main climate, of course, control everything upstream and downstream sea level
10:59 and falls do not propagate. The propagate ups upstream is too to
11:07 That's actually called the bathwater talk about as a consequence, controls on limitation
11:16 different in upstream areas, functionaries dominated by the tectonics upstream area. Climate
11:26 . Area down street There is a more sensitive to just so happens that
11:34 explorations focused on sedimentary basins in upstream tend to be generational lance games.
11:43 if we're trying sentiments, the basin controls foreigners in the 70 face for
11:51 sing. Some of those same relationship of control for what happened. You
11:59 just, you know, we talked little about the idea of strong.
12:07 are another batteries have some importance in of strategic. One of it.
12:13 of them, this thing called. here we have River Line represents to
12:23 traditionally represents now, depending on how about 50 m 10 minus five.
12:42 when the Mississippi River is at the , right top river is at is
12:50 scene The river is at sea level years. Where is the basis?
13:10 15 minutes. Backwaters point base, river Fine Mississippi that doesn't occur
13:22 About 500. Okay, the backwater the channel that divided by a smoke
13:30 m by 0000 is is is 500,000 , and this about 400 kilometers controls
13:52 salty the water is started. Yes, so the ability of the
14:01 fledged at four billion saltwater is determine called the the same thing. Because
14:16 Baylon is a language limit of salt incursion. Then we also have to
14:22 all the time with that infested land live it. You're talking. That's
14:30 controls like ability, votes controls Billy Living Grade. Read a Fistric.
14:39 feel through systems. It's very sensitive the bath water affects his affair.
14:45 that one. Then there is the for the title of that water with
14:56 faces, blood graves time cross bedding a line works with land would live
15:04 from. Actually all those have four on the rest from the From the
15:12 , Facings controls reservoir quality in quite . They also had very important
15:25 With that perfect content scales thousands of backwater effects of systems of pretension to
15:37 where I work. Scared of tens I have an important defection. The
15:47 Families way have a variety of downstream extreme controls. Some of the back
16:01 they talked about the fact that status operate over a lack of insightful so
16:08 to hundreds of thousands of years. effects for over 100,000 years, it
16:13 . Climate calls very strong. James weather deposition yes, forced final changes
16:26 controlled Forward cycle with lack of exactly tends to hundreds of years. Now
16:37 an example Off buttress effect. So case we have, they see were
16:44 actress. This can occur. Just out a building seat belted seaward ruptures
16:53 It's a green represents the new buffer that would result in your combination.
17:01 yellow represents area failed in the deposition the interest because saying that area C
17:14 a combination so greenest sea level rises you see with shit. Then Green
17:28 represents the new movie. A which will produce a wedge of sediment
17:33 . Very. I saw that some the examples very forest exercise. Of
17:44 , if you gracie the new wedges that is the three wedge that's yellow
17:52 , which a short example. As result, to see that this invites
18:09 turns that we've been dancing around after means exactly that you're on a road
18:19 . Some point you've got to stop find accommodations. Space where you could
18:24 accommodations this face for space available for to come to rest. Four more
18:34 . So the technical definition is space for seven. Of course, the
18:40 fats face change the rent that space created, accumulation refers to weather and
18:50 . Settlement action fills with the Represents strange that's available for attention even
19:02 you're in central 3000 away, meters from the shoreline. Still get just
19:11 out. Win dust that comes in solar that will soothe classic scene.
19:22 , there's not much accumulation there because is so pretty. But nevertheless,
19:29 get red dust for a little red . Layers represent extraterrestrial for your adjacent
19:41 a confident margin. Large dollar of course, whether or not you
19:49 accumulation. Offence for Mary. If a shallow shelf and it's in the
20:01 car factory turns on and you get nation Larry, Small Swiss. We'll
20:14 about him next. Next lecture tomorrow . We're gonna do a little a
20:23 class exercise here. I'm going to yourselves. How this and I'm gonna
20:33 you start with with a person okay me, half is a river that's
20:45 . That means this case has which destroyed for settlement from right off.
20:53 where this just just fucking loads. combination of the base is zero.
21:01 patient is no ability to accept Seven determined Maris lost. Used to
21:08 accommodation far for receptive combination. Sometimes talk about the A s ratio combination
21:21 several fried my response for race, know, which is the set of
21:29 versus so in the case, the set this fire ations very low.
21:38 no accommodation. Instead of the supplies , it comes in those sentiments stupid
21:47 and after another with me. So a deposition environment in the face?
21:54 here's Here's a sentimental facing all I do His friends were setting What kind
22:01 what kind of a deposition Marvin have a gradation als developed. That would
22:11 a place of deposition. That's what better. One set of stops for
22:19 case. Settlements moving through Going out British once a deposition since they always
22:33 one option. What else? You we've got to you could have a
22:44 systems floating through flowing through could lose passing through a little family place.
22:54 stops. I'll give you the only . Yes, a receptive value.
23:07 huge cans it except all settlements And it's so golf space left in
23:16 case, the spaces. So we set up feeding in process and a
23:25 . That sentiment is falling in the , falling down for the basin and
23:32 . So what kind of deficits in bar means Was this from history?
23:42 customer? Sarah, What's the nature the deposition? Cheryle, given example
23:56 a deposition assistant. Yeah, I what else? What else? Fans
24:23 me. BC a little bit, missed the first green alluvial van.
24:32 still don't get it this distortion. know, you're a fan a little
24:40 deeper in some, so I just just want you guys appreciate it.
24:48 I've given you is just ridiculously said seven passes through because there's no a
24:56 in the bottom. There's way too accommodation. High set of five,
25:01 not enough to combinations. Too much for Senator Master. For weeks,
25:06 predicted Dentist is there. Now let's about Middle Case. Seven comes in
25:15 it gets stored system, but not to pass through right, but that
25:21 combinations not so far right that we deformed. So you have a only
25:30 in here deposition assistant. You think might find a Phil? Exactly
25:45 So we predicted all the major deputised just fine. Barry, instead of
25:49 accommodation, that's how simple Small Street out back in 1960. The concept
26:02 sedimentary strata, graft, racket changes in combination. Seven. And
26:10 we can predict those way know about age with tectonics, the base in
26:18 basin is writing to someone on that . You made that basis that that's
26:28 that's help all you have sauce You know something about tectonic setting.
26:35 might expect size facing Mr Feed that that becomes critical for resolute because it
26:45 you get That's where you work for to do. This is a
26:57 We're just gonna lost money. A to keep track a few things.
27:05 is now going to see stripping This is from the S P
27:10 Straight, a website. This was by Christopher Jeans was very Maybe that's
27:27 character what this is showing. Lower , lows fallings rising, falling,
27:40 that he shows me a cross section section. You should have a strong
27:49 a little boat there tells you where way towards. Right now we're in
27:56 time of rising sea levels shoreline because attract the fabrication. Then it's
28:13 Now we're falling. Get decision figure for something that were forming stage.
28:22 we started seeing lives. Now he to get filled. Finally Just don't
28:30 for his job back And Dari violence systems. Then the shorelines turns around
28:40 starts to get next fall. I just looking at 14 time so falling
28:58 gonna get this sequence. Very They're sitting batteries. Not much.
29:04 a small draw is not. You get big incision because of shots from
29:08 was exposed. This is a small . That's a big been a small
29:14 base. This is the word. much bigger draw. Get those massive
29:28 on a submarine going to this massive wise to sea level rise.
29:36 is a maximum flooding surface, so between transgressive franchises funding sort of turnaround
29:44 stuffing and following stages. Do it last time. This is the presidency
30:00 , but not enough to get major . Just information those fans transgression,
30:11 , stalls get more Russian number six that's a big drop. Suffering.
30:22 maximum Russian. They started an that feeling there's the first big transgression
30:30 beginning expressive systems that's actually transgressions. is really hurting for those eyes,
30:49 others more subtle. Grady says that huge draw is that a good rest
30:59 relative to some of the sands that those more. Yeah, that's before
31:04 next face of 4 g. And when those fans get positive assault,
31:09 environment, get started incidents, that's classic suddenly turn activation. Zealand's all
31:26 , very firmly in basis. All samples of suddenly place. All I'm
31:37 do is with myself kind of basic . How combination and seven is flying
31:46 showing a cross section process really It's Sony Pictures on one page with
31:58 . No, Hold it. Mystic , See across three 3 14 Understanding
32:10 the state of tried to go through factories time explaining the first one slowing
32:19 . Forced geometry and terminology reflects the get your brave from the patterns for
32:28 . You could sort of look at pants. Why, No, that's
32:32 that's still standing after wise knowledge. to do is build your understanding process
32:42 to physically figure technology Used language probably food that gets in the
32:53 Do you understand the concepts processes term means, if you understand processes that
33:03 do you understand in your So in bone case, we have Step one
33:12 the Exxon High Sentiments A five son a bitch looks for life subsidence zero
33:19 see all the changes. No no see. So we get what
33:27 of red strongly to get. So I could do a test. I
33:31 show this warrant Factory. What's Short is that curve, not
33:49 I appreciate the fact matching Joseph is that's that's good for everybody. So
33:56 this is it this so that for I take it is there? Is
34:13 any aggravation? So is you can't know gonna be this? So what
34:27 it just towards Yes, Exactly. ? Purity results. See, I
34:34 the idea now in this scenario, we do is add a please,
34:39 add a bit of accommodation. This combination here was in the next
34:46 if we're adding a bit of subsidence we had a now each position with
34:52 shoreline has to rise. Joseph, you've got. Now you can connect
35:00 off. Okay, Draw that which is? That's terrible. From
35:13 force of a force in 18 Now, in the middle case,
35:21 have a situation where some supplies exactly . Okay, so now what?
35:38 ? No, 100%. That's 107 , man. Now, certainly.
35:54 over. Now it's migrating in that . That's 100%. All right.
36:10 . Is there any a former that's for in this renovation? And but
36:18 this case, it looks like it's transgression of that. Here. You've
36:23 erosion as a result of expression. talk. Have no deposition central.
36:36 my interaction with questions cause I think get it. I understand. Know
36:42 everyone's. I know what group. of you will be a bit lower
36:48 others, but that's far. Did get it? If you're confused,
36:55 please don't be afraid. Just wave hand. It's a stable get
36:58 I'm not sure, but I'm getting addressing the nation. One thing I
37:08 a hard time understanding is when you're about the original surface expectation that
37:15 You know, I forget the boundary . You know, when you first
37:19 the first example? No. Does always occurred? You're always gonna have
37:24 original relative performance found here. So question, I think the other example
37:42 a little bit easier that distinction. basic erosion processes that we're gonna worry
37:54 . What is it? Rose? . That's typically where? Rivers
37:59 Because of points, They got roast Kirsten. Excited, freshen for
38:05 Field last. I'm talking about that , except okay, so I didn't
38:14 it at the end of explaining this . Get a rose in your
38:18 That's the first one of mentioned image but the rocks with their transgressive surface
38:26 . And then there is a regression with others that occurs through falls.
38:33 are two different things. And explain thoroughly in subsequent lecture is actually
38:40 That has moved into the last part this lecture. That idea. It's
38:47 great question. Unless you're if that answered for substance. So what's
39:00 One of things that's missing this dog so here. We have harsh on
39:08 a p a r a r What's ? A for for this doctor
39:34 Exactly. That's missing for the next . Joe's heirs of degradation Here we
39:42 sometimes referred to as a correctly. should be called a positive accommodation high
39:51 of surprise rising. But there's Seven applied to get a regression.
40:00 get a classic AP combinations. I see all represented deposition during Falls
40:13 Seals. Okay, we have to to think about this concept, this
40:20 for into directory a little bit for . So it's a We sort of
40:29 up various positions of shoreline ceiling That's what that dash line dashed line
40:37 . The position of the strong line each increments of the degradation of this
40:44 be a great industrial. What it is that the degradation of the shoreline
40:54 is a little is that red There is steeper. The smoke of
41:01 base slope of the basis is Dash line number wine that's formed five
41:11 trajectories falling sea level, steeper down So what that means is this area
41:21 here there used to be a quiet insurance suddenly starts to feel fence of
41:30 hinging on a previous quiet service. waves with rode away the shelf that
41:39 erosion. That service road was called progressive surface off. It's an erosion
41:49 five million processes that occurs as a of regression. In this case,
41:56 progression is forced drop with that term service of Florida. Sometimes it was
42:08 Esten. Now see, we also a drop of 11 in this
42:16 drop of semen so slow that scene writhe angle of trajectory. Fall produces
42:25 sloping line that's listening, then the floor over withdrawal. What that means
42:33 sentiments produced during father phone. Reduce of settlement, that recipe field into
42:41 and deeper water, such that we a figure of 50 pot of settlements
42:47 the Deposition of Climate. For it shows you a movie that shows how
42:52 front of forms like his chances. notice that now there's no longer an
42:59 surface separates the marine sands from the . Now there's no oppressive structures,
43:09 , the river that's running across the of that service is rolling into the
43:17 . So in the upper case, get definitive erosion surface, and then
43:22 love that you get a regressive surface indicates street, that's more smooth.
43:37 . Excuse me. Existence. So for the police. Again. Let
43:42 let the corner join to the Oh, I'm sorry. Again.
43:51 to join to the class. I have access to let them.
44:02 Okay. Okay. Little do I will, uh, see if
44:17 could give you permission to. So gonna make you a co host,
44:33 ? Yes, Yes, please. you. Allow you to She was
44:40 . So that way, luckily, table flythe catch up. So just
44:56 on. So So in this we get to surfaces in once a
45:03 drama because the projections of false in case check terrific directly falls must.
45:11 the road only emotional sort of begins the river is all the whole system
45:21 and in the case, be get fall that produces the line. That's
45:26 same as the sea floor. And once again, we don't get an
45:32 surface there with rivers this creative now got to the emergency services. Some
45:42 disfigures called Progressive Services as a sequence . Others will call service, so
45:53 fallen seem quite complex. Strata graphics controls the trajectory for the steepness of
46:03 true victory? It's primarily five Fraser up for versus the smoke monthly basis
46:13 which the fall of hers versus the face today. So this is falling
46:27 the races. Talk to see Phone just doesn't suitable for all
46:38 Fine, you stand fall, get basis. Deciding rapidly still resulted in
46:45 little increase in combination. It is basis for faster the substance increases differential
46:59 probably or passive margins for bases It says it's not chicken complicated,
47:06 it is a combination of geometry. radio was the basis for all changes
47:10 of substance and then the rain. then I introduced this idea off.
47:23 you connect up points of the that's the show breaking strong line.
47:30 can see when Horace awful ready for introductory this case. Family interment fees
47:42 terms of later termination, the rate aggravation with Tom, this case assistant
47:48 , strong in front rating and then . Then it becomes a graded
47:55 In this case, we have stronger that comes more formulations in this
48:03 accommodate is increasing slowly, then more . So it was. The space
48:08 more rapidly system for today. In case, maybe the maybe see that
48:14 rising. Starts to slow down. face constant so builds vertically. And
48:21 combination slums Now for more pictures. me, that combinations constant instead of
48:31 , it starts off slow and instead instead of service front from four strong
48:35 its able to go from So these these projections would be controlled by either
48:42 fire for accommodation. Have a for assumptions of diagram like this, this
48:55 between each of these show so flat . Let's say that this represents have
49:03 that 10 times time for that one time. It's not true. Your
49:14 knows you could dig deeper these diagrams complicated terms flawless patrolling notionally various things
49:27 might control to know exactly what is sanitation for unique certain that for any
49:40 no substance, you don't always Just tell you that a big part
49:48 my research right now. Not right . You guys for not letting you
49:56 . That's the froth. Estimate Ready sedimentation. Distraught from level. Now
50:11 frustrated about it? A little bit trouble. And that leg, the
50:18 guys t think systems trash terminology, said, Well, it was
50:25 maybe you should think about want So they picked up on this idea
50:33 off staffing matters and aggravation, Formulation recommendation, state for observations that throughout
50:41 particular sure you got dreams came up a neutral technology. They referred to
50:49 as a combination successions succession means And idea is the stacking patterns reflect changes
51:00 combination diagrams in one form or we're now on the fourth time through
51:16 , Do you receive system that goes horizontal aggregation? What is that?
51:48 But this one is just a ap feet and then it goes to exactly
52:02 one is so that was the combination 18 that off very straight for those
52:19 changes in combination to seven. In case, the combination is less than
52:27 , which means that settlement wells and face that glasses always be regressive and
52:37 decreasing, goes negative, which means . Which is which means that it's
52:44 that against its slower and slower it 18 75 accommodation. It was
52:54 In this case, accommodation outstripped has choice but to back a yes
53:04 Great run ! Get arrested Recreational successor . Success that makes sense more.
53:16 understand these diagrams easier. You understand case, they draw secrets. Family
53:23 , Which marks the point of matching . Decision of rigors of deposition.
53:28 to see? Here's a T Excellent Guy centers is a p de
53:38 the fallen stage A marks, But we're gonna introduce a systems tracks
53:48 is that whereas these geometries I think you see a with him with you
54:02 . So so fastening combination successions This is the most up together in
54:09 diver. What? They say 18 green. Okay, Pete a represents
54:20 foreign and then all represents the I take that back to traditional fraternity
54:28 Hiestand on. Just understand blue is systems a p d. I stand
54:38 . Those fans for is is transferring high standards separately for no stand by
54:46 young conformity for the secrets boundary passes systems tract is mortified. A point
54:57 fox maximum progressive surface, which course that is the same as a transgressive
55:04 that's orderly and by a thin layer fat step units reaches a point of
55:09 transgression that marks next forming surface systems around the match of funny surfaced and
55:18 of next progressive for operational stances. the combination successions and in the lower
55:30 around the show strong with little faces space various services that for the area
55:42 of reservoir interest for some fans. valleys, lo stat shorelines. So
55:56 so. We start with his turning sat stacking pounds of combinations,
56:02 that in terms of those according to , I congratulate staff doing. And
56:10 what we're doing in geology is we with the observations off the faces.
56:15 sections face tryto for processing. What doing today is explaining processes a short
56:26 . Explain what happens that result. hope is that by spending a last
56:31 this as we move forward, start getting it just really get cross
56:37 of beach systems. Yeah, like Based on the explanations for Donald,
56:49 right to that because frankly, fourth of the eyes is is to help
56:54 process. I feel that because once finish this lecture, I will go
57:01 exercise. And hopefully, by doing exercise, we have a choice.
57:15 now, I would suggest with Jason five, um, for at 6
57:26 another 15 minutes of lecture to I can push forward to finish for
57:31 could take a break and resume for guys. Let's finish out. That's
57:37 finish. So I showed a lot a lot of cartoons. Here is
57:44 is a real size before it's pretty that you've got uniforms. The scale
57:50 is 10 kilometers by three seconds, there's probably 1000 2000 m. This
57:58 about 100 kilometers call sectors. So is a big regional size of a
58:05 , and it's pretty fair that you see feed a pro grading platforms fax
58:11 another set of appropriating uniforms. These like their rating. Okay, these
58:21 like they're retrograde dating trading. So basically shows you could look at free
58:26 chronic forms, seismic section, and troubling combination successions. Okay, the
58:34 s stands for this case. aggregation, seafood set. That's a
58:42 confusing. All that means that this a very full scale unit. There
58:48 small units with their small sequences, size differences, their love of resolution
58:57 all. Explain all that talk about of data in a later lecture.
59:04 is off the evolution of a The only thing on the star
59:14 That's difference is we now have a face, one of those on the
59:21 . This is just a syriza of sections. This is the oldest,
59:26 , the youngest. So what this is Tony, for the horrors off
59:30 is a combination of the vertical axis old subsidence and see them. So
59:38 totally accommodation. Okay, if you time off, accommodation increases, but
59:47 see it's currents over rated increases, so is the rate of accommodation is
59:56 but increasing more smoking time, obsession, fisheries, everything except for
60:15 systems, grating and grating. general aggressive. It's parading, but
60:23 got aberrational. Proponent of the degree aggregation increases as the combination increase
60:30 They're going to be which the period CIA falling for what we predicted falling
60:42 better. Three based on was So now we get there is a
61:00 point's degrading that is begins to want scan Master of 10. I think
61:16 Exercise I gave to Do gave today's this information with a little bit of
61:22 . So get the sequence battery for stage period for that between Deanna,
61:30 get rapid rise. So what happens get a rapid rise to get 80
61:35 all rapid rise so I can get friends I saw literally. You're
61:45 The man Virginia with a trance. prevention, which scared increasing combination but
61:52 down we get another. But if look at these cross sections again,
61:59 could attribute them according to changes. not explicitly specified? Mr. Graham
62:09 set up sort of sort of hidden then heading down to explain which systems
62:19 her on called in various stages of . Now we talked also about falling
62:31 of sea level. So this is example we see that was falling.
62:36 down. Starting shorelines. So one a 345 The lower case what a
62:47 integrating In the first case that rate degradation is relatively slow, so three
62:55 attached to forced after 35 is attached three in the lower diagram rate of
63:03 as much around. So we get series of detects falling. I think
63:10 might be irresolvable. This probably I come back to explain. We'll have
63:18 guitar lecture on this lady introduced to . One of the key background,
63:30 things. That Elijah. Very simple . But all it says is that
63:43 the only pathologies faces those that somebody yourself. The dog. Dr.
63:56 a river. There's there's a There's the dealt off. There's verdict
64:05 Delta deposits on pro down because they're there is the Delta. There is
64:12 pro delta. I just dealt pro . Adults front stands feel about
64:19 There it is. There's adults. stands made over live. And guess
64:25 kind of one separates what separates Except for the fishing line, the
64:44 over mines adults from there is the right across the river. Deposit that
64:51 , a dumpster falls it. Another may follow. Here is student
65:00 drilling out problems. Walther's law usually to vertical successions. Feds gradually we've
65:09 sands and muds go up just 44 . Lessen the shells on the transition
65:17 , so get a gradual forces in succession that follows. So that's a
65:30 of all critical issue is always looking surfaces that violate is straight forward
65:42 So what would explode? Finally, abated shelter. And then suddenly you
65:50 flu rocks running into the Marine That's not right. Small Syrians that
66:00 deposits that feeds out should have a that that's really falls away down because
66:11 being eroded away. Something's missing. don't live next to throw down.
66:19 what I want to show. River it. So if you see a
66:23 for the positive, eroding away down a pro doubt, that probably represents
66:29 fall of sea level five. This how we start to use Walters law
66:36 interpret. Here's an example. So a metric section that shows a succession
66:46 stations recorded violent Russians for short. were land by interpret, Mickey sand
66:57 and finishings That's overly bottom nice to face beach, because it and just
67:09 that for short banks, is overlaying the beach witness. Then There's short
67:17 the separatist milestones from the beach ball . Now let me ask first if
67:25 transfer s a beach, what will the next of ardent? See what
67:32 beach for the next environments. Transitions ? No, they just for
67:48 Exactly. So waltzes. Law, you have a recipe for succession
67:56 Deposition forces Walter Doltish Four Short years Depositions What's missing. Four sources.
68:16 pieces missing family transitions. Two environments deposition for Mrs of that content.
68:23 that that almost with that flooding service by Joseph enormously anonymously super toeses distant
68:34 folks stones for beach that's not That violates small. Therefore, that's
68:42 key sequence. Photographic surface we called of. It's not, but what's
68:52 is you have to be able to environments of deposition correctly identify that.
69:00 . The second case, we have slew of your deposit that's eroding into
69:05 product. Normally posit that would be product. So the only way to
69:14 through deposit floating it out by degrading river down into more distant face so
69:23 represent certain for five policy point that be secret rating was, that's how
69:36 use this juxtaposition of faces. Of , there are evolves for identifying surfaces
69:46 that makes sense. Review a lot these concepts. We'll get a formal
69:56 . Nothing we talked about was this of forced with Russians, where we
70:01 dropping a stroll on the results of forces of See Rebel. And what
70:07 does is produce this produced regulations for , and the degree off separates the
70:14 lines, maybe function of free So here we have gradually falling.
70:20 that it falls vigorously, slows begins to rise. This is where
70:27 get into the question of jokes fast During the rise. Noticed that first
70:34 formed during the falling stage is a during so waves mushrooms about circles and
70:42 rode away. There wasn't much there begin with. Jenny phone. What
70:48 does that change? The seafood fans by a pharmacy in places it five
70:55 transgressive rose on your left. Is live deposit that surface, that which
71:04 too coarse. Moved, by the , get a strategy. Isolated those
71:13 deposit that separates the high stand by five passes that bypass surface coral voice
71:21 far later the point that the system out. You get roses here.
71:30 your mortgage in this diagram, where put a short things over in a
71:36 deposit, having this transition forms, that progressive surface of roses I talked
71:45 . This is what it might look one out. This is another example
71:54 that complicit of time I want to out. This is just another example
72:01 shows sort of closer profits. Apple five brought of sea level Fallujah
72:13 depending on on how vigorous waving roasting . A lot of surface that was
72:21 by the fantasy speaking Spanish is formed the fall results in rose by rivers
72:30 maybe no arose the Waynes very white away from land area by vigorous
72:40 , of course. All in the against river, just transgressive, forming
72:45 green rest. I had some depending have erosion by rivers. Those who
72:56 preservation come back to that story, this next get with. It was
73:05 a team of from school in your ways. Onshore semester waves from that
73:17 in symmetry in the short run searches have more energy form strong unless officer
73:27 forces can you mind very much so builds the surface. That's all the
73:37 face that's certain filled up settlements positive that service for that short. And
73:50 could be a very efficient frozen One. Transgressions. Furs that short
74:02 The debts towards the end of world occur to find my way face.
74:10 a lot of settlement. I'm just wipe out 50 m, everything shoreline
74:17 the murders of 5 m deep. rivers go for eroded by that 10
74:26 . Transgressing emotion is intense. There's dog around. Illustrates that the senator
74:31 short waves that picture of transport all results. Aggressive erosion. Five waves
74:39 transgression works. So here's three. 10 years ago. That's 4000 years
74:53 transgression. The Green Circus represents the of religion. Surface Retzer is
75:03 You notice that the Green service is to read. De found is preserved
75:10 this area here that's gone natural. five. Transgressive surface. That's a
75:20 for the projectionists. As that Forget opportunity. Surface. Very explosion
75:28 your phone. Sea level secrets finding place transgressive surface only preserved with rivers
75:36 deep enough that erosion 9 m in places, the world's transgressive erosion.
75:49 a common. Here's yet another Those races contacted transgressive AP accommodations that
76:05 transfer. Rest. There's an area wills orange represents, the true taken
76:11 here and positive sea waves move. is just the first TV showing area
76:20 wage along during class. There's a of that petals scattered and that's that's
76:39 so we could think about secrets. about three. You start off this
76:47 by short one to moving cross section how I looked at lacrosse action that
76:59 looked at three. Slip back and across actions issues. So here is
77:08 I started. Traditions. Dropsy level lands, flat word deposit, submarine
77:19 . High standards of some fans. troll lines. Dropsy. Rebel
77:24 One area former submarine can again. suddenly fan there. Uh, and
77:31 French. Okay, then we showed movie Rising sea level. If it's
77:41 enough rise to become settlement for vacation for upgrades. Finical falling stage know
77:48 assistance for there's a fast that pushed back with Rollins system. They
77:55 Coming rise with continues to furthering exposes points to get a decision, suddenly
78:02 that position transgression. Daddy films, expression. He starts to take
78:11 Overwhelms start maximum flood when the system around. Should have brought down sections
78:25 this match. Right. Sounds look a single measure. Section intervention such
78:35 lecturers. Start reading into into the . Stop here. You're 10
79:16 One thing I thought about it but no there. And the good
79:23 is I wanna make sure your money that long. What I'm gonna ask
79:33 is we just In the last 10 that we have, I'm just gonna
79:44 one last thing. Okay? This the exercise to work off. What
81:22 is just a flat area curving shoreline . First, some people saying probably
82:03 that so face. Okay, four guys. That's something in race that
83:06 subject. Okay, So what? like to do this somebody strong
83:43 That's right. With I like to is first of all for morning.
84:19 stay there. All right? Love ventures. That is pressing question.
85:21 understand now. Yeah, I don't . No. Yes. This one
85:48 every day. So you have. . I thought today pretty well.
86:47 . I'm sorry. I just don't a camera with me. I got
86:51 new PC, so I don't have camera yet. There's no investment
