Dynamic Earth: Pangaea, CDT, Plate Boundaries, Rocks

Who is the person credited with developing the theory of continental drift?

• Aldrin Weiner

• Galileo Galilei

• Alfred Wegener

• Isaac Newton

What was Pangaea?

• It was a supercontinent, made of all the landmasses on Earth.

• It was 2 separate land masses, one on the Northern Hemisphere and one on the Southern Hemisphere.

• It was a supercontinent made of 3 landmasses

• It was the name of an ancient organism

What was included in the Continental Drift Theory?

• The continents used to be joined together to form a supercontinent.

• The continents have since drifted apart to their current or present location

• Pangaea was formed around 250 million years ago

• All of the above

What evidence did Wegener use in his Continental Drift Theory?

• Continents fitting together/matching-up like puzzle pieces

• The same plant and animal fossils found on continents separated by vast oceans

• Mountain ranges and coal deposits line up across continents

• All of the above

Why didn't other scientists believe in Wegener’s theory?

• He could not explain how the continents moved.

• He didn’t have evidence

• His data was wrong

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