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

What evidence did Wegener use in his theory?

• Continents and fossils fitting together/matching-up like puzzle pieces 
• glacier scars and evidence from temperature
• mountain ranges and coal deposits line up across continents
• all of the above

How long ago is Pangea believed to have existed?

• 200-300 million years ago
• 1000-2000 years ago
• 10,000-20,000 years ago
• 20-30 billion years ago

What does the word Pangea mean?

• big land mass
• old land
• all land

How does evidence of glaciation in Africa support the Theory of Continental Drift?

• It shows that the continents must have been in a different location.
• It doesn't. 
• I shows that it was colder at the equator in the past.
• It shows that it was warmer at the equator in the past.

The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of

• subduction
• plate tectonics
• evolution
• seafloor spreading

What are the remains of organism noticed by Wegener that are found the same in two continents?

• Leaves and flowers
• Ice and mountains
• Plants and animals
• Dinosaurs and reptiles

This is a picture of glacier scars found in Africa.  What are these evidence for?

• Africa has always been near the equator
• Africa was once in an area of the Earth that had a very cold climate
• The continents have not moved
• sea floor spreading

The continents move very slowly, only a few __________per year.

• meters

• kilometers

• centimeters

• miles
