1.  The diagram below shows three beds of sediment deposited at different times in a quiet body of water. The sediment deposited in each bed is best described as:

A. sorted mainly according to particle size
B. sorted mainly according to particle shape
C. a mixture of sorted and unsorted particles
D. showing no evidence of sorting

2.  The greater the time that stream sediment is transported, the greater probability that the sediment will become more:
A. angular and smaller
B. angular and larger
C. rounded and smaller
D. rounded and larger

3.  Which factor has the most influence on the development of soil?
A. climate
B. longitude
C. amount of rounded sediment
D. slope of the landscape

4.  The diagram below shows granite bedrock with cracks. Water has seeped into the cracks and frozen. The arrows represent the directions in which the cracks have widened due to weathering. Which statement best describes the physical weathering shown by the diagram?

A. Enlargement of the cracks occurs because water expands when it freezes
B. Thid type of weathering occurs only in bedrock composed of granite
C. The cracks become wider because of chemical reactions between water and the rock.
D. This type of weathering is common in regions of primarily warm and humid climates.

5.  Base your answer to the following question on the Earth Science Reference Tables and on your knowledge of Earth Science. A stream entering a lake deposits sediments on the lake bottom in the pattern shown on the map below. Which corner of the map is nearest to the point where the stream flows into the lake?

A. northeast (NE)
B. northwest (NW)
C. southeast (SE)
D. southwest (SW)

6.  Which rock material was most likely transported to its present location by a glacier?
A. rounded sand grains found in a river delta
B. rounded grains found in a sand dune
C. residual soil found on a flat plain
D. unsorted loose gravel found in hills

7.  Base your answer to the following question on the Earth Science Reference Tables and the diagram below. The diagram represents two branches of a valley glacier. Points A,B,G, and H are located on the surface of the glacier. Point X is located at the interface between the ice and the bedrock. The arrows represent the general direction of ice movement. Which force is primarily responsible for the movement of the glacier?

A. ground water
B. running water
C. gravity
D. wind

8.  Base your answer to the following question on the diagram below, which shows ocean waves approaching a shoreline. A groin (a short wall of rocks perpendicular to teh shoreline) and a breakwater (an offshore structure) have been constructed along the beach. Letters A,B,C,D, and E represent locations in the area. The size of the bulge in the beach at position D will:

A. decrease
B. increase
C. remain the same
D. move to location E

9.  The map below shows some features along an ocean shoreline. In which general direction is the sand being moved along this shoreline by ocean (long-shore) currents?

A. northeast (NE)
B. southeast (SE)
C. northwest (NW)
D. southwest (SW)

10.  The block diagram below shows a portion of Earth's surface. If the climate in this area becomes more humid, which change will most likely occur?

A. The landscape features will become more rounded
B. The elevation of the entire region will increase
C. The limestone will stop dissolving
D. The rate of wind erosion will increase
