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

Which key component should be included in a presentation on Alfred Wegener's hypothesis of continental drift?

• There are two types of plates, continental and oceanic.
• The continents' movement causes land features.
• Convection currents in Earth's mantle move the plates.
• The continents appear to fit together like a puzzle.

All of the following are evidence of continental drift EXCEPT:

• similar rock layers on separate continents
• similar fossils on separate continents
• artifacts left by early humans
• tree fossils found in places trees do not grow

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

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

Why did no one believe Wegener's thoery?

• 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
