Chapter 13 Test

 

Indicate True or False for each of the questions below.

 

1.      Earth’s moving plates are actually pieces of the lithosphere.

 

2.      Over geologic time, Earth’s magnetic north pole has become the magnetic  

     south pole and vice versa.

 

3.  Belts of earthquakes and volcanoes are found at plate boundaries.

 

4.      If you were exploring the deep ocean and saw a mountain range with a deep valley running through it, you would be observing a collision boundary.

 

5.      The Appalachian Mountains may have formed when North America, Africa,   and parts of Europe were converging.

 

6.  When a continental plate converges with an ocean plate, the ocean plate will  

     slide over the continental plate.

 

7. North America is the only continent that has a craton.

 

8. Thin-skinned thrusting is the movement of horizontal sheets of rock inland

    from continental margins.

 

9. A terrane contains fossils, which differ from those found in neighboring rock

    formations.

16. The coolest rocks in the lithospheric plates are

           

a.      closest to spreading centers.               c. at boundaries where plates are               

                                                                        sliding past one another.

b.      the farthest from spreading centers.    d. in the volcano belts.
