Plate Tectonics and Continental Drift

The San Andreas Fault in California is known as an active earthquake area. What type of

boundary is it?

• Converging

• Diverging

• Transform

• Sea Floor Spreading

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

The theory of continental drift states that all the continents were once part of one big landmass called Pangaea. Who was the scientist that came up with this theory?

• Harry Hess

• Bill Nye

• Alfred Wegener

• Albert Einstein

Which of the following evidence was used to support theory of continental drift?

• Continents fit together like a puzzle

• Similar fossils were found on separate continents

• Different types of rock, mountain structures, landforms are found all over the world.

• All of the above

• Only A and B

If you took rock samples from the Mid-Atlantic Ridge, the youngest rock would be

• located where the plates collide

• located at the place where rocks are furthest from the rift valley

• Located at the center of the ridge (rift valley), where oceanic crust is formed

• none of the above; all the rocks would be the same age

Why was Alfred Wegener unable to explain his theory?

• He couldn't explain how the continents drifted.

• He couldn't explain why similar fossils on different continents were separated

• He couldn't explain why similar geological structures found were found on different continents.

• He couldn't explain why the continents fit together like a puzzle.
