Continental Drift

Who is the German Scientist that came up with the theory of the Continental Drift?

• Albert Einstein

• Ms. Stukel

• Galileo

• Alfred Wegener

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

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

• North America

• Antarctica

• China

• India

When Wegener looked at maps he noticed African and South American ____________ lined up.

• Lakes

• islands

• Hills

• Mountain Ranges

What is the force that moves the continents?

• Conduction

• Convection

• Radiation

• Conveyor belts

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.

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

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 do you call the supercontinent landmass formed million years ago?

• Pangea

• Asia

• Pantallasa

• Eurasi

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
