Continental Theory

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

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

• Harry Hess
• Galileo
• Alfred Wegener
• Newton

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 other climate evidence from temperature
• mountain ranges and rocks 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 enough evidence
• His evidence  was wrong
• He didn't use the right technology to gather data

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

Was continental drift accepted in Wegener's lifetime? 

• Yes
• No

Mesosaurus fossils are found between where?

• India
• Africa and South America
• Antartica
• Australia
