Continental Drift

Which type of plate is older?

• continental
• oceanic

What type of plate is thicker?

• continental 
• oceanic

What is the name of the supercontinent that formed from about 200-100  million years ago?

• Pangaea
• Laurasia

What is an underwater mountain range where new ocean floor is made?

• subduction
• mid-ocean ridge
• deep-sea trench

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 are the two continents the fits together based on Wegener's Theory?

• Asia and Russia
• India and Asia
• South America and Africa
• Africa and Asia

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

Where did Wegener find plant fossils that today would not be able to survive on that type of land?

• North America
• Antarctica
• China 
• India

The Appalachian Mountains in the U.S. match up with a similar mountain ranges in northern Europe. How does this support Wegener's theory of Continental Drift?

• The mountains were formed after tectonic plates had moved away from each other

• The similarities provide evidence North America & Europe were connected when the mountains formed.

• Similar rock samples were found on the ocean floor and at the two mountain ranges indicating that they both formed around the same time.

• This evidence does not support the theory of continental drift.
