Answer each question by selecting the correct blue button. Only the first answer selected is graded.

1.  The diagram below represents zones within soil and rock. The zones are determined by the kinds of movement or lack of movement of water occulting within them. What is the deepest zone into which water can be pulled by gravity?

A. aerated zone
B. capillary fringe
C. saturated zone
D. impermeable zone

2.  Flash flooding often occurs in city areas because:
A. runoff decreases during precipitation
B. ground water storage is usually very large
C. roads, pavements, and buildings reduce the infiltration of water into the ground
D. the heat generated by city areas decreases actual evapotranspiration

3.  The diagram below represent two containers, each filled with a sample of nonporous particles of uniform size. Compared to the sample of larger particles, the sample of smaller particles has:

A. lower permeability
B. higher permeability
C. less porosity
D. more porosity

4.  The diagram below represents a geologic cross section of a location in Texas where an oil well has been drilled into the bedrock. Oil, water, and natural gas can collect and stay in the sandstone layer because sandstone often:

A. has a grain size ranging from fine to coarse (0.006 fo 0.2 cm)
B. is composed mainly of grains of quartz
C. contains air spaces, making it porous and permeable
D. metamorphoses to quartzite

5.  The diagram below represents two identical containers filled with samples of loosely packed sediments. The sediments are composed of the same material, but differ in particle size. Which property is most nearly the same for the two samples?

A. infiltration rate
B. porosity
C. capillarity
D. water retention

6.  Base your answer to the following question on the Earth Science Reference Tables and on the diagrams below. The diagrams represent 500-milliliter containers that are open at the top and the bottom and filled with well-sorted, loosely packed particles of uniform size. A piece of screening placed at the bottom of each container prevents the particles from falling out. The sample in which container would have the greatest capillarity when placed in water?

A. sample (A)
B. sample (B)
C. sample (C)
D. sample (D)

7.  Which conditions produce the most surface water runoff?
A. steep slope, heavy rain, and frozen ground
B. steep slope, gentle rain, and unfrozen ground
C. gentle slope, heavy rain, and frozen ground
D. gentle slope, gentle rain, and unfrozen ground

8.  What is the main reason that a high concentration of aerobic bacteria is harmful to a lake?
A. The bacteria release large amounts of oxygen
B. The bacteria use up large amounts of oxygen
C. The bacteria cause excessive cooling of the water
D. The bacteria provide food for predators

9.  Points are plotted on the graph below to show the relationship between lake-water pollution and the population density around several small lakes in New York State. As populaton density increases, the lake pollution:

A. increases
B. decreases
C. remains the same
D. decreases rapidly

10.  The table below shows the relationship between total yearly precipitation(P) and potential evaportranspiration(Ep) for different types of climates. The total yearly percipitation (P) for a city in Texas is 218 millimeters. The total yearly potential evapotranspiration (Ep) is 951 millimeters. Which type of climate does this city have?

A. humid
B. subhumid
C. semiarid
D. arid
