What can we learn about the scientific process from Alfred Wegener's experience?

Old theories should change as new data is gathered.

What observation got Alfred Wegener thinking that the continents could fit together?

The continental coastlines look like they fit together.

What key information was Wegener missing when he presented the Theory of Continental Drift.

He could not explain how the continents moved.

Geologist have found that coal in Antartica is older than coal in Wyoming. Why is this?

Antarctica was near the equator first and kept moving.

How did the Scientific community react to Alfred Wegener's theory?

He couldn't show how continents moved so they didn't believe

Where would you most likely find the North Pole?

A, because glaciers form in cold polar environments.

In the Pangea lab each group produced slightly different models with the same data. Why?

Every scientist with interpret data a little differently.

How did lack of technology affect Wegner's Theory of Continental Drift?

In 1912, scientists didn't know the Earth wasn't solid.

Why were land reptiles a key piece of evidence that the continents were once connected?

It was the only way they could be found on every continent.

Why is Continental Drift the most likely cause of coal layers in Antartica?

Coal could only form if Antartica was once by the equator.

What is the major problem with using the present continental shapes to construct Pangea?

Wind and erosion have changed the shapes of the continents.

We find evidence of past glaciers in Australia, what is the most logical explanation for this?

Australia must have been much closer the South Pole.

What source would provide reliable data on moving continents?

A set of data showing geologic properties of continents

If you only have folded mountains to reconstruct Pangea. What geologic knowledge will help you?

Folded mountains form when continents crash together.

The Appalachian Mts are the same as mountains in Norway and Scotland. How does this support CD?

N. America and W Europe must have collided in the past.

In the Pangea lab what key piece of evidence helped you locate the equator?

Coal forms in the tropics, so the equator was found there.

Which line would best represent the equator?

Line 1 because coal forms along hot climates along equator.

Answers

1
What can we learn about the scientific process from Alfred Wegener's experience?
We shouldn't change old theories they are fact.
Sicentists are always looking at new ideas & accept them.
Old theories should change as new data is gathered.
Science is unreliable because it changes
2
What observation got Alfred Wegener thinking that the continents could fit together?
The continental coastlines look like they fit together.
He could feel the continents moving.
Moving continents have been seen on other planets
People on all continents look the same
3
What key information was Wegener missing when he presented the Theory of Continental Drift.
He needed maps of Pangea.
He needed to know how coal formed.
He was not a real scientist so he did not have their respect
He could not explain how the continents moved.
4
Geologist have found that coal in Antartica is older than coal in Wyoming. Why is this?
Pangea must have never existed.
Antarctica was near the equator first and kept moving.
Coal used to form under ice before it formed in swamps.
The earth must have had two equators when it had two suns.
5
How did the Scientific community react to Alfred Wegener's theory?
They were angry that he would now be famous.
He couldn't show how continents moved so they didn't believe
They were glad to see a theory different from land bridges.
They were glad to see a new theory tying together evidence.
6
Where would you most likely find the North Pole?
D, because we don't have data to determine N pole
Location B because it's in the center of the continent.
A, because glaciers form in cold polar environments.
C because coal forms in cold environments
7
In the Pangea lab each group produced slightly different models with the same data. Why?
One group was exactly right, and the rest were wrong.
Even with new data, a theory in science can never change.
Because the data was fake, no correct model is possible.
Every scientist with interpret data a little differently.
8
How did lack of technology affect Wegner's Theory of Continental Drift?
The Space Station didn't have good cameras in 1912.
He wasn't able to travel when collecting data.
There were no discoveries before 1912.
In 1912, scientists didn't know the Earth wasn't solid.
9
Why were land reptiles a key piece of evidence that the continents were once connected?
It was the only way they could be found on every continent.
They showed that these animals could fly, swim & float.
Proved that these animals could migrate across the oceans.
It proved there was only one organisms on the continents.
10
Why is Continental Drift the most likely cause of coal layers in Antartica?
When earth's oceans boiled away only coal was left.
Coal could only form if Antartica was once by the equator.
A very hot Earth would heat the poles not the equator.
Coal only forms in cold climates.
11
What is the major problem with using the present continental shapes to construct Pangea?
Wind and erosion have changed the shapes of the continents.
Accurate maps from the past do not exist for reference
Changing borders of countries affects the continents shapes.
Pieces of earth have flown in to spaces and are now missing.
12
We find evidence of past glaciers in Australia, what is the most logical explanation for this?
The Earth was farther from the sun at that time.
The earth must have frozen over in an ice age.
Australia must have been much closer the South Pole.
Glaciers must be able to form in warm climates
13
What source would provide reliable data on moving continents?
A farmer's journal showing how crops grow in other lands.
A newspaper story about Eskimos lives vs ours.
An old legend about dinosaurs living in Utah.
A set of data showing geologic properties of continents
14
If you only have folded mountains to reconstruct Pangea. What geologic knowledge will help you?
All Mountain ranges run North to South.
Folded mountains form when continents crash together.
Mountains have snow on top, so they are not at the equator.
There is none. Mountains are completely random.
15
The Appalachian Mts are the same as mountains in Norway and Scotland. How does this support CD?
N. America and W Europe must have collided in the past.
There is no relationship between this mountain ranges.
All mountains are the same age
Mountains are created in the same way
16
In the Pangea lab what key piece of evidence helped you locate the equator?
The equator moves with the continents so its hasn't changed.
Coal forms in the tropics, so the equator was found there.
The equator ran through the Africa just like it now does.
The equator always runs through the middle of the continents
17
How does Earth preserve evidence of past events?
Glacier deposits tell us a continent was close to the poles.
Plant & animals fossils tells us what climate they lived in.
Coal layers tell us a continent was close to the equator.
All of the above
18
Which line would best represent the equator?
Line 1 because coal forms along hot climates along equator.
None of the above. You cannot find the old equator.
Line 2 because it is in the middle of the continent.
Line 3 because there are mountains along the equator.
