Zones within soil and rock are classified by the water movement occurring in the zones. Which diagram best represents the most common arrangement of these zones?

• A

• B

• C

• D

Which combination of processes from the water cycle is most likely to cause flooding?

• low runoff, high infiltration, high condensation

• high runoff, low infiltration, high precipitation

• high runoff, low evaporation, low precipitation

• low runoff, low evaporation, high transpiration

How could a long-term decrease in precipitation impact an area?

• It could decrease the amount of possible infiltration in the area.

• It could increase the average water level of lakes in the area.

• It could increase the amount of flooding in the area.

• It could decrease the possible amount of damage to crops in the area.

1. Which set of surface soil conditions on a hillside would result in the most infiltration of rainfall?

a.

b.

c.

d.

• steep slope, saturated soil, vegetation

• gentle slope, unsaturated soil, vegetation

• steep slope, unsaturated soil, no vegetation

• gentle slope, saturated soil, no vegetation

Which condition would cause surface runoff to increase in a particular location?

• having a decrease in the annual rainfall

• reducing the gradient of a steep hill

• covering a dirt road with pavement

• planting grasses and shrubs on a hillside

During a heavy rainstorm, runoff is most likely to occur if the surface soil is

• loosely packed sand-sized particles
