What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

What was Pangea?

• An ancient Mountain Range that divided Africa
• A large valley where civilization began.
• A supercontinent where all Earth's land masses were joined.
• A large meteor that hit Earth and destroyed all of the dinosaurs

The circular arrows inside the Earth's Mantle represent what type of motion, that drives ALL plate movement?  

• Convergent Boundary
• Ocean Currents
• Convection Currents
• Transform Boundary

A Subduction Zone occurs, when one more dense plate subductions under a less dense plate, what type of boundary could this be considered?  

• Convection Current
• Convergent Boundary
• Transform Boundary
• Divergent Boundary

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

• Harry Hess
• Galileo
• Alfred Wegener
• Newton

Mr. Jones, an archeologist, travels to study land animal fossils from millions of years ago.  He has found fossils of the same land animals in eastern South America and western Africa.  Which conclusion best supports Mr. Jones' findings? 

• The 2 continents were once joined together as part of a larger continent.  
• Land animals found from fossils collected from the west coast of Africa are similar to the ones found on the east coast of South America
• Early Europeans became Zombies as a Result of the Rock coming to save the world in the movie San Andreas
• The animals developed on the two continents at the exact same time

Andrew found warm-weather plant fossils while on an expedition to Antarctica.  Which conclusion best supports his find?  

• The seeds of plants were carried by flying dinosaurs that escaped Jurrassic Park
• The island was once closer to the equator, but has since drifted to its current location
• Ancient Mariners transported the plants to the island.  
• The plants drifted on the ocean currents to the island.  

What is Plate Tectonics?

• movement of the Earth in space

• movement of the oceans against Earth's land

• movement of the Earth around the sun

• movement of the pieces of Earth's crust

Which piece of evidence was use to prove continental drift?

• The shape of the continents
• Similar fossils found on separate continents
• Tree fossils found in odd places
• All of the above

This piece of evidence that Alfred Wegener used to prove the continents were once connected involved finding remains of once-living organisms on different continents.

• jigsaw evidence

• fossil evidence

• rock evidence

• None of the above
