Continental Drift Theory

What evidence did Wegener use to support 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

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

Originally the Continental drift theory was not well received by other scientist.  Why? 

• There was a competing theory at the time that was more believable. 
• There was no data showing the continents ever moved. 
• The scientists did not know the force responsible for moving the continents. 
• The scientist presenting the data was unreliable.  

What is the force that moves the continents? 

• Conduction 
• Convection 
• Radiation 
• Conveyor belts 

When Wegener looked at maps he noticed Africa and South America ____________ lined up. 

• Lakes
• islands
• Hills 
• Mountain Ranges 

What are the three types of Evidence that supports Alfred Wegener's Theory? 

• Fossils, Fish, and Land
• Sedimentary, Magma, and Climate
• Fossils, Land forms, and Climate
• Climate, Land forms, and Metamorphic rock
