Continental Drift

What is this a picture of?

• plate tectonics
• continental drift
• pangea
• glacier scaring

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 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 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

What two specific continents fit together most noticeably?

• Africa and North America
• South America and Europe
• South America and Africa
• Antartica and Africa

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

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

• Harry Hess
• Galileo
• Alfred Wegener
• Newton

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

According to Wegener's hypothesis of continental drift, 

• Earth's surface is made up of seven major landmasses
• the continents DO NOT move
• Earth is slowly cooling and shrinking
• the continents were once joined together in a single landmass

What is Pangaea?

• the name of a German scientist
• the name of the super-continent that existed millions of years ago
• another name for continental drift
• the name of an ancient fossil
