Continental Drift

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 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

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

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

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.

What is the force that moves the continents? 

• Conduction 
• Convection 
• Radiation 
• Conveyor belts
