| 00:04 | Okay. I'm glad so many of brave the onslaught of probable Archy, |
|
| 00:14 | , whatever it will be, if you have a friend who you |
|
| 00:20 | is in this class, it didn't it today. Please let them know |
|
| 00:24 | some instructions will be posted on Because I could see about Looks like |
|
| 00:30 | half the class to show up And I don't know if I'll have |
|
| 00:35 | on Monday. They had not said campus is reopening, we'll just have |
|
| 00:39 | see, uh, but I wanted go ahead with this anyway, because |
|
| 00:44 | two classes too much for me. , so we're gonna do the exercise |
|
| 00:50 | plate tectonics today. Everybody has And right now, just a map |
|
| 01:00 | we're gonna assume somebody has decided where boundaries are. So the instructions are |
|
| 01:08 | , get into teams of about four or three people, so subdivide yourself |
|
| 01:16 | , get yourself set closer. For of you that are gaps between |
|
| 01:19 | rearrange yourself for not more than that . You enjoy it. Wait, |
|
| 02:56 | . You start there, You You okay? Wait. Wait For |
|
| 05:48 | , Okay. Does everyone have their ? Okay, there's two different kinds |
|
| 05:56 | data on here. What I call data. So everyone has one of |
|
| 06:02 | , right? Everyone sees their black for plate boundaries. Where does this |
|
| 06:09 | go? I'll be on the other . I remember that when you're hollering |
|
| 06:16 | because what's over here might continue over . That one is this morning. |
|
| 06:29 | just they have some students who forget my projections air from globes and that |
|
| 06:35 | don't get things going around from one to the other. They have what |
|
| 06:40 | call Matt faults where this might You might decide this is one kind |
|
| 06:46 | boundaries. You call it a blow it over here. You call her |
|
| 06:53 | . What is really the same Okay, so everyone has that. |
|
| 06:57 | , so we have the data I got it upside down. I |
|
| 07:02 | . I was doing this in a . I have what I call point |
|
| 07:07 | , which are these guys. But points and this is points. And |
|
| 07:12 | is what I call Ariel Data. two on the top. Everyone understand |
|
| 07:17 | kind of data you have. Depends on what it iss This woman |
|
| 07:26 | thoughts that are different. Colors are , earthquakes there where earthquakes have |
|
| 07:34 | Not only is it where it's that one is color coded by how |
|
| 07:40 | the earthquake waas. So you have on here for red means shallow. |
|
| 07:47 | think it's blow. Is that the ? Once this one is volcanoes. |
|
| 07:53 | just red dots for world Volcano. . You have this one. You're |
|
| 07:59 | and this one is very simple. the simplest one. You got that |
|
| 08:05 | so and then we have the aerial . That's one is what we call |
|
| 08:11 | chronology the age of something on the . In this case, it's the |
|
| 08:17 | of sea floor, and the colors correspond to that age, with red |
|
| 08:26 | the youngest and blue being the oldest . And then this one, it's |
|
| 08:33 | the highs and lows of the The topography on both the C four |
|
| 08:42 | the continent. The blue collars are zero elevation in the sea floor to |
|
| 08:52 | minus death. And then the collars from white too green to rent four |
|
| 08:59 | for heights on the earth. So looking at this and you have your |
|
| 09:07 | map. So now you want to your maps and see how the plane |
|
| 09:14 | Lee the plate boundaries. You don't about the rest of the world. |
|
| 09:18 | ? How? The plate boundary corresponds whatever your group data is. I |
|
| 09:25 | the easiest thing to do is our these things and go like this and |
|
| 09:32 | how your data core response to something the plate boundary. So I have |
|
| 09:41 | you some. This is in the . What? It's also here. |
|
| 09:45 | you have a point Data, how your points? How are they distributed |
|
| 09:52 | those point boundaries? Are there lots points? Are there a few |
|
| 09:58 | Are the points on one side of data off your plate boundary or they're |
|
| 10:04 | on the plate boundary? Or are on both sides? Yes. So |
|
| 10:11 | don't write it down. Write it on the back right now because then |
|
| 10:16 | going to decide how many different types like boundaries you have. You are |
|
| 10:23 | to decide how many different kinds of founders you have for this data. |
|
| 10:29 | that might be a data. A with no data. So that's what |
|
| 10:34 | one. Yeah, just include, there's no data like there are place |
|
| 10:43 | that go up here. Is there data, you know? So that's |
|
| 10:47 | kind of plate boundary. One with data or this guy, their |
|
| 10:54 | But the reason that the oceans there's few data points there. But that |
|
| 10:59 | be a data kind with not And are they write on the boundary |
|
| 11:05 | they offset the plate boundary off South here is just offshore. So I |
|
| 11:14 | watching earthquakes there. They're offset from boundary, and they go from shallow |
|
| 11:20 | deep. So that's another kind of boundary. Does everyone understand howto classify |
|
| 11:27 | boundaries? No. Okay, maybe draw something. Okay, Which one |
|
| 11:45 | I do? I'm not gonna do of them. Okay? You all |
|
| 11:51 | me to do your data set? , I'm ready. Oh, |
|
| 11:59 | no. I'm not going to the one. Give it to me. |
|
| 12:04 | hardest run is the sea for age . So there's a plate boundary. |
|
| 12:17 | thought I had done pointer options Okay, there's a plate boundaries that |
|
| 12:32 | through the middle here. There's a in the top where there's no |
|
| 12:39 | so I'm going to have long be data. There's a dollar boundary here |
|
| 12:51 | has data right on the boundary. is the same on both sides? |
|
| 12:57 | goes from dark Magda light red to to green in some places blue. |
|
| 13:03 | it's what I call some metric so , too. So I didn't get |
|
| 13:14 | symmetric. Okay, Another plate boundary is, You hear? You can |
|
| 13:27 | there's blue on one side and red the other. So it's what I |
|
| 13:33 | call asymmetric. Does everyone get Just the colors. There's no when |
|
| 13:49 | say it like I have a plate , which is a current line. |
|
| 13:58 | , not the squares and the color , either side of the plate boundary |
|
| 14:02 | . Not so here. There's no on it. But on one side |
|
| 14:06 | it is bloom. On the other of that, This fight by under |
|
| 14:18 | one side of it is blues. side of the head, these blobs |
|
| 14:21 | colors so you can see that the is not the same on either side |
|
| 14:27 | that boundary. There's actually another kind play foundry in here. I'm not |
|
| 14:33 | do it because now I've given away of that map. So those of |
|
| 14:41 | are doing it. See if you find another kind of plate boundary on |
|
| 14:46 | and everybody do this now on their map. Okay, So then what |
|
| 14:50 | do is I have a box. you didn't bring them. I have |
|
| 14:56 | box of color pencils to each one these that you've written a description about |
|
| 15:02 | saw in a collar. And then you do is like, I don't |
|
| 15:11 | different car. So this would be type one boundary and you car only |
|
| 15:21 | boundary. I don't care about the in the middle of agreement or in |
|
| 15:27 | middle of the United States. I want you to figure out what is |
|
| 15:32 | along the plate boundaries with respect to data type. Does that make sense |
|
| 15:38 | saw, then? All right. . I'm not getting my pen. |
|
| 16:02 | world. Then you come boundaries. rest of class discuss this gallery of |
|
| 16:10 | . When you when you have your with all these colored, you are |
|
| 16:15 | to go. No. You want map because we're going to do something |
|
| 16:20 | with your math on Monday or the time We have class cheesy. Keep |
|
| 16:26 | for now because you're gonna have groups a different exercise. You go ahead |
|
| 16:33 | keep that. Okay? There You can ask questions of Mei |
|
| 16:41 | Have free tea, a spiral. and Chris help us too. |
|
| 19:00 | wait, wait. This way. think you're going. Wait. All |
|
| 24:12 | . Wait, wait, wait, . E don't think like that. |
|
| 33:16 | going down, right? Like a way |
