Evidence of Pangaea

What did Alfred Wegener propose in his continental drift hypothesis?

• Continents were formed by volcanic activity.

• Continents were once part of a single supercontinent. that slowly drifted to their current locations.

• Continents have always been in their current locations and will remain unchanged.

• Continents are shrinking over time. causing oceans to widen.

The Theory of Continental Drift introduced the idea of Pangaea. What is Pangaea?

• One of the ancient animals that helped Wegener prove that fossils from different continents originally came from the same location
•  supercontinent that existed in Earth's distant past
• The underwater ocean range in the middle of the ocean
• The hot spot which gave rise to the Hawaiian Islands, among others

Wegener found fossils of ancient ferns on Antarctica, this shows

• That some ferns can survive temperatures well below freezing

• That humans put ferns on Antarctica millions of years ago

• That Antarctica moved over time from a warmer location where plants could grow

• That fossils can be formed in cold climates

Why did other scientists have a hard time believing Wegener's theory of continental drift?

• He could not explain how the continents moved

• He didn't have enough evidence

• His evidence was wrong

• He didn't use the right technology to gather data

The Appalachian Mountains in the U.S. match up with a similar mountain range in Northern Europe. How does this support Wegener's theory of Continental Drift?

• The similarities provide evidence that North America and Europe were connected when the mountains formed.

• The similarities show that the continents must have been closer to the equator at some point in time.

• This does not provide any evidence to support his theory.
