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

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 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 was Wegener able to PROVE before his death?

• The mid ocean ridge existed

• convection currents cause plate movement

• Greenland was moving away from Europe a tiny bit each year

• Africa and South America were connected

The OLDEST seafloor is located?

• Farthest from the mid-ocean ridge

What kinds of evidence were used to prove that the seafloor spread?

• Pillow lava, age of rocks, WWII shipwrecks

• Age of rocks, magnetic seafloor stripes, WWII ship logs

• Pillow Lava, magnetic seafloor stripes, age of rocks, SONAR

What technology was used during WWII to detect enemy submarines and produce the first map of the seafloor?
