Yeah Oh okay People More aspiring science figure One thing

00:09

right here shows the strata Graphic relationships of some of

00:13

the great Plains formations Strata graphic columns show older rocks

00:17

the bottom and younger rock units toward the top going

00:21

right there All right so here it is That's the

00:23

data representing you on all the crap is study Okay

00:27

And they can kind of skim all this stuff if

00:29

you need Teo Here we go On the basis of

00:36

the data presented which member of the Brule formation is

00:40

further south through information Gonna find that on the map

00:44

here in second Well time to hit rock bottom Here

00:49

We're dealing with the lowest part of the figures that

00:51

rule formation You say that with a mouthful of marbles

00:54

All right tilt your head to the left You'll see

00:56

that the Brule formation has two members poolside and Whitney

00:59

The sharp information is clearly distinguish from the rule formation

01:03

Be right there with the Raz sandwiched between him as

01:07

in see right there so we can exclude those from

01:10

consideration right off the bat Now how do we know

01:13

which one is further south The Whitney or the pole

01:16

side Well if you can't remember where South Dakota is

01:19

relative to Nebraska you can look further up to see

01:22

that the labels for directions are given at the top

01:25

of the figure And we must say we really bounce

01:28

right back up there after hitting our all time low

01:30

Yeah well the geologic units and features on the right

01:34

hand side of this column are farther south than those

01:37

on the left hand side Therefore the Whitney member is

01:40

the correct answer So yeah it's just a That's it

01:44

for Whitney Whitney and wit need with it Never mind
