Question 1

1.

What does the theory of continental drift state?

The continents were once joined in a super-continent and have moved over time

The earth is broken into lithospheric plates that moved at one time and are now stationary

Continents have always been stationary and do not move

None of the above

Question 2

2.

The Appalachian Mountains in the U.S. match up with a similar mountain range 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 and 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

Question 3

3.

What layer of earth is responsible for the movement of the tectonic plates?

Inner Core

Outer Core

Asthenosphere

Atmosphere

Question 4

4.

The mid-ocean ridge is an underwater plate boundary where new land is being created from cooling mantle. What type of plate boundary is found here?

Convergent

Divergent

Transform

Subduction

Question 5

5.

The mid-atlantic ridge is an example of a divergent boundary where new land is being created from magma rising from the mantle. During the process of seafloor spreading, where can the youngest land be found?

At the center of the mid-atlantic ridge

Closest to the continent

100 miles from the mid-atlantic ridge

Furthest from the mid-atlantic ridge
