Transcript

00:00

Yeah Oh okay Next up Tts spire Science That's what

00:06

we're doing here Figure one thing right here shows the

00:10

strata Graphic relationships of some of the great Plains formations

00:15

Strata graphic columns show older rocks the bottom and younger

00:19

rock units and toward top right there All right so

00:22

here it is That's the data representing you on all

00:25

the crap is that we're studying and they can kind

00:28

of skim all this stuff you need Teo Which of

00:36

the following conclusions is best supported by the data All

00:40

right well let's see here The unnamed ash is older

00:43

than the sharp formation of judgment Olden Hearts It's all

00:46

about age here so well if you're feeling pressured to

00:49

answer this question just imagine how those rocks feel all

00:52

layered on top of each other like that right lot

00:54

of pressure Well the description above figure one mentions that

00:58

strata graphic columns display older rock units at the bottom

01:02

and younger ones toward the top we'll sink The unnamed

01:05

Ash unit is below the Sharps formation Well it's the

01:09

older of the two So the answer here is a

01:13

The unnamed ash is older than the sharp information right

01:16

Well the other way to answer this question just to

01:18

look at the dates listed on the right hand side

01:20

of the figure Right over here The unnamed Ash unit

01:22

closely lines up horizontally with that thirty point five eight

01:27

million years ago While Sharp formation has a date list

01:30

that have twenty eight point six million years ago it

01:32

is therefore younger than the unnamed Ash unit Two years

01:36

ago the bigger the number of the older it is

01:38

You're still really old Sharp formations though Don't worry You

01:41

were just not unnamed Ash Hole You know I can't 00:01:44.65 --> [endTime] be there yet
