Question 1

What type of motion is found at a transform plate boundary? What physical feature marks the boundary between the two plates?

Accepted Answer

At a transform plate boundary two plates slide laterally past each other. A transform plate boundary is the site of a transform fault.

Question 2

What two features of the magnetic field do magnetic iron-bearing minerals that crystallize out of magma record?

Accepted Answer

The minerals record the strength and direction of the Earth's magnetic poles at the time of crystallization.

Question 3

Paleomagnetic data plotted on a map suggested that the magnetic pole had moved over time; this phenomenon was called ____________________.

Accepted Answer

polar wandering

B)  friction created by tidal forces generated by the Moon. 
C)  conduction of heat within the mantle. 
D)  convection of heat within the mantle. 
E)  convection of heat within the core.

Question 5

What other geological processes could have resulted in the configuration of coastlines so that South America and Africa appeared to fit together?

Accepted Answer

Wegener's critics pointed out

Question 6

Earth's magnetic field is dipolar, meaning that it has two similar magnetic poles one at the north pole and one at the south pole.

The differing paleomagnetic records for each continent showed:

Accepted Answer

A)  each continent had its own magnetic pole during successive geological periods. 
B)  that the magnetic poles for each continent had moved over geological time. 
C)  that the magnetic poles have remained in one location and each of the continents has moved. 
D)  that both the poles and the continents have moved over time. 
E)  none of these
