Question

In a series of rock layers, a geologist finds fossils of a pine trees and oak trees in layers that are 1.0 m and 1.5 m deep. However, in a layer that is 2.0 m deep, he finds fossils of tropical plants and trees.



Which explains his findings?



A.


The continent shifted toward the tropics.


B.


The continent remained in the tropics.


C.


The ancient climate remained hot.


D.


The continent shifted toward the mid-latitudes and polar regions.

Answer 1

Is it B?

Answer 2

about Prevailing winds

Answer 3

Sounds like geology, not history...

I do not think it is B.

Answer 4

The deeper the layers are, the older stuff is. So that means the deepr you go, the more past you are talking about.

Answer 5

then D?

Answer 6

because since its older it went from the tropics to the colder areas where pine grew

Answer 7

Yah, it will be C or D. Of those two, D is more likely...

Answer 8

would Prevailing winds questions work in history? this is how they are set up (not the band)

Answer 9

Generally all the geo/earth stuff goes in Geography. I tell people to tag me on it because I took geology. Helps with some of that.

Answer 10

may i post it in this question set? so it doesnt take any other question tabs

Answer 11

Actually we are not worried about how may questions get opened over time. More that are posted helps people have more chances for medals, etc.

Answer 12

could you help me with a "How are prevailing winds setup?" and a Latitude question?

Answer 13

Well, I will have to see them to know.

Answer 14

How are the prevailing winds set up?


A.


Uneven heating sets up a general circulation pattern from the equator to the poles. Earth's rotation breaks it into six cells and deflects the surface winds.


B.


Earth's rotation sets up a general circulation pattern from the equator to the poles. Uneven heating breaks it into six cells and deflects the surface winds.


C.


Uneven heating sets up a general circulation pattern from the poles to the equator. Earth's rotation breaks it into six cells and deflects the surface winds.


D.


Earth's rotation sets up a general circulation pattern from the poles to the equator. Uneven heating breaks it into six cells and deflects the surface winds.

Answer 15

that type

Answer 16

it tells me how they work but not how they are set up

Answer 17

Hmm... I did not go over that...

Answer 18

then how about this one

Answer 19

Which is the correct explanation for 40°N latitude?



A.


all positions along a circle that runs perpendicular to the equator and 40° east of it


B.


all positions along a circle that runs perpendicular to the equator and 40° west of it


C.


all positions along a circle that runs parallel to the equator and 40° north of it


D.


all positions along a circle that runs parallel to the equator and 40° south of it

Answer 20

Obvious.... C... didnt look at the directions it mentioned.. XD

Answer 21

Hehe

Answer 22

What patterns in the magnetism of the rocks along the oceanic ridges explain seafloor spreading?



A.


The rocks on one side of the ridge were aligned in one direction, while the rocks on the other side of the ridge were aligned in the opposite direction.


B.


The magnetic patterns periodically reversed only on one side of the ridge.


C.


The magnetic patterns periodically reversed and were symmetrical on both sides of the ridge.


D.


The magnetic patterns showed only one direction but were symmetrical on both sides of the ridge.

Answer 23

thats my hardest one :I

Answer 24

OK. So, any clues on it? I do know what it is, but lets see what you think and why so I can talk to you about it.

Answer 25

This is why i called this 1 the hardest one XD i had breifly went over this part of science and didnt get it, or i wouldnt have asked this one xP

Answer 26

Couldnt it be A?

Answer 27

Do you know what sea floor speading is?

Answer 28

the formation of new areas of oceanic crust, when occurs when 2 parts of mid ocean ridges move outward

Answer 29

Yes. So, it starts on this crack:

and moves out in both directions.

That both directions is important. So, any of your answers have a problem with both directions as a key idea?

Answer 30

C?

Answer 31

that is the only one that is meaning with goind Outward with Both sides

Answer 32

Yes. And the symmitry is what they used to prove that it was happening!

Answer 33

my last question is the prevailing winds one XD

Answer 34

pre·vail·ing wind
noun
plural noun: prevailing winds

1.
a wind from the direction that is predominant at a particular place or season.
that is the google deffinition

Answer 35

Yes, but that does not talk about the system.

Answer 36

its all about earth's rotation

if the earth stopped rotating the prevaling winds would cease

Answer 37

Yes, well, that is because of the heating and cooling of sun and not sun.

Answer 38

Crossing fingers. i hope i pass this XD i can only take this once

Answer 39

OK, so really the question is things like does it go from the poles to the equatior or equator to poles.

Answer 40

So, what would be the correct one?

Answer 41

I am looking at that page I lined, and I see equator to poles in there. So that eliminates two answers.

Answer 42

So its A or B

Answer 43

so is it uneven heating or the earths rotation?

Answer 44

A. Uneven heating sets up a general circulation pattern from the equator to the poles. Earth's rotation breaks it into six cells and deflects the surface winds.

B. Earth's rotation sets up a general circulation pattern from the equator to the poles. Uneven heating breaks it into six cells and deflects the surface winds.

Those are equator to the poles. So the thing is to look for other key terms on that page.

Answer 45

Lets see my score

Answer 46

Wow....

Answer 47

i was 1% off >.>

Answer 48

you were right on prevailing winds.

Answer 49

Well don't have too much fun.
