Continental Drift

• Alfred Wegener a German scientist discovered that the continents looked like they fit together

• He needed evidence to prove this Hypothesis

Evidence Of Continental Drift

• Fossils were found from the same species on different continents

• The same plant Glossopteris was found on all of these continents which means they had the same plants and climates

• Mountain ranges in the U.S. (Appalachian Mountains) match up with mountain ranges in Europe

Continental Drift Theory

Stated that the earth’s continents were once all a super continent called Pangea and eventually separated and drifted apart.

Multiple Choice

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

• Harry Hess
• Galileo
• Alfred Wegener
• Newton

Multiple Choice

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

• North America
• Antarctica
• China 
• India

Multiple Choice

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.

Multiple Choice

What is this a picture of?

• plate tectonics
• continental drift
• pangea
• glacier scaring

Multiple Choice

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
