Base your answer to the following question on the photograph below, which shows a
mountainous region cut by a large valley in its center.
5. What characteristic of this large valley supports the inference that glacial ice formed the valley?
6. The table below describes the deposits that an observer saw while walking downstream along a
500 meter section of a streambed.
It could be inferred from the above data that the stream's velocity
1) was constantly decreasing 2) was constantly increasing
3) decreased and then increased 4) remained the same
7. Why do the particles carried by a river settle to the bottom as the river enters the ocean?
1) The density of the ocean water is greater than the density of the river water.
2) The kinetic energy of the particles increases as the particles enter the ocean.
3) The velocity of the river water decreases as it enters the ocean.
4) The large particles have a greater surface area than the small particles.

Base your answer to the following question on the Earth Science Reference Tables and the
diagram below. The diagram shows air movements associated with cumulus cloud formation over
a lake during a summer day. A, B, C, and D are reference points.

1) decrease as its volume decreases 2) decrease as its volume increases
3) increase as its volume decreases 4) increase as its volume increases

16. A sample of rounded quartz sediments of different particle sizes is dropped into a container of
water. Which graph best shows the settling time for these particles?
1) 2) 3) 4)
17. The velocity of a stream is decreasing. As the velocity approaches zero, which size particle will
most likely remain in suspension?

cross section best represents the settling pattern of these particles?
1) 2)
3) 4)
19. Two streams, A and B, carry the same volume of water, but stream A has a greater velocity.
The most likely cause of this greater velocity would be that stream A
1) has more tributaries 2) has a wider streambed
3) flows down a steeper slope 4) travels over less resistant bedrock
