C. deposition
D. vulcanism

2.  The best evidence of crustal uplift is provided by:

B. shallow-water marine fossils found in deep ocean water
C. horizontal sedimentary layers
D. thick layers of sediment on the ocean floor

3.  Base your answer to the following question on the diagram shown below. The diagram shows a model of the relationship between Earth's surface and its interior. Mid-ocean ridges (rifts) normally form where tectonic plates are:

A. converging
B. diverging
C. stationary
D. sliding past each other

4.  The block diagram below shows the bedrock age as measured by radioactive dating and the present location of part of the Hawaiian Island chain.

A. south
B. east
C. southwest
D. northwest

5.  Base your answer to the following question on the map below. The map shows the locations of deep-sea core drilling sites numbered 1 through 4.

A. (1)
B. (2)
C. (3)
D. (4)

6.  The theory of continental drift suggest that the:
A. continents moved due to changes in the Earth's orbital velocity
B. continents moved due to the Coriolis effect caused by the Earth's rotation
C. present-day continents of South America and Africa are moving toward each other
D. present-day continents of South America and Africa once fit together like puzzle parts

7.  Which inference is supported by a study of the Earth's magnetic rock record?
A. The Earth's magnetic field is only 2 million years old.
B. The Earth's magnetic field is 50 times stronger now than in the past.
C. The Earth's magnetic poles are usually located at 0 degrees latitude.
D. The Earth's magnetic poles appear to have changed location over time.

8.  In 8 minutes, an earthquake P-wave travels a total distance of:

B. 4,700 km
C. 6,600 km
D. 11,300 km

9.  The cutaway diagram below shows the paths of earthquake waves generated at point X. Only P-waves reach the side of Earth that is opposite the focus because P-waves:

A. are stronger than S-waves
B. travel faster than S-waves
C. travel faster than S-waves
D. can travel through liquids and S-waves cannot

B. Point (E)
C. Point (F)
D. Point (G)
