Continental Drift Theory

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

• Harry Hess

• Galileo

• Alfred Wegener

• Newton

What is this a picture of?

• plate tectonics

• continental drift

• pangea

• glacier scaring

Which type of information was NOT collected by Wegener to support his continental drift hypothesis?

• glacial deposits

•  fossils

• seafloor magnetic data

• rocks

How does fossil evidence support Wegener's hypothesis of continental drift?

• Similar fossils are found along continental margins that appear to join together.

• Fossils are found in areas where the present-day climate could not have supported the organisms that made the fossils.

• Similar fossils of giant, land-dwelling dinosaurs are found on continents separated by oceans.

• all of the above

The theory of continental drift named a key part of this idea 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

Why was Wegener's theory not accepted?

• He had no proof of how they were moving

• He had no evidence

• He was married

• He was not a Scientist

What evidence did Wegener have for his theory of continental drift?

• He had no good evidence.

• He knew that plant and animal fossils as well as rock layers matched up in South America and Africa.

• He explained how the continents moved

The similarities between the Appalachian mountains and the Scottish highlands provides evidence for which process?

• fossilization

• climate change

• continental drift

•  glacial retreat

What piece of evidence supporting continental drift states that present day glacial deposits are found at the equator?

• puzzle pieces 

• rock and glacial deposit evidence

• fossil evidence

• mountain range evidence

The Theory of Continental Drift states that Pangaea broke apart and the continents "drifted" away from each other

• True

• False
