Pangea + Continental Drift

Where was North America located when it was part of Laurasia?

• Near Europe and Asia

• Near South America and Africa

• Near Asia and Australia

• Near India and Australia

Will our current map of Earth always look the same? Explain your answer.

• No, the continents will disappear.

• Yes, the continents have finished moving.

• It depends on climate change.

• No, the continents are still shifting.

What do we know about the continents we have today?

• They have stopped moving due to plate tectonics.

• They formed when Pangaea split apart.

• They formed when Pangaea split apart.

• They will never form another supercontinent.

How does the formation of the Ural Mountains prove the idea of supercontinents?

• They are the oldest mountains formed during Pangaea.

• The mountains have moved like the continents have moved.

• Europe and Asia collided to form the mountains.

• They were formed when North and South America collided.

Why did it matter that tropical plant fossils were found in Antarctica?

• It supported the idea that the continents used to be connected and then drifted.

• It supported the idea that people had migrated from the tropics to what is now known as Antarctica.

• It supported the idea that the southern hemisphere was once in the north and vice versa.

• It supported the idea that tropical plants can actually grow in cold climates.

In the fall of 1911, what was one of the problems Alfred Wegener saw in the theory that the Earth was unchanging?

• It didn't account for the coastlines of some of the Earth's continents.

• The idea of land bridges or stepping stone islands between continents had been debunked.

• It couldn't account for identical fossil evidence being discovered on different continents.

What evidence did Wegener NOT use to support his idea of continental drift?
