1 .		The hydrologic cycle operates across the entire surface of the planet, from several kilometers below ground level to several kilometers above it.   True  False
2 .		As water evaporates from a lake surface, there is a release of latent heat to the lake, and a resulting increase in water temperature.   True  False
3 .		Potential evapotranspiration is the amount of water that would evaporate and transpire under optimum conditions.   True  False
4 .		Compared to an evaporation pan, a lysimeter is a simpler, but less accurate, device for determining potential evapotranspiration.   True  False
5 .		The wilting point is the point at which soil particles contain only hygroscopic water, which is unavailable to plants.   True  False
6 .		As soil-moisture recharge removes soil water, plants must exert greater effort to extract the same amount of moisture.   True  False
7 .		Permeability is the amount of pore space in soil.   True  False
8 .		The zone of aeration is the part of the subsurface in which pores are not completely filled with water.   True  False
9 .		The height to which water can rise without the aid of pumps is refered to as the aquiclude.   True  False
10 .		A confined aquifer is less susceptible to surface pollution than is an unconfined aquifer.   True  False
11 .		Aquifers can collapse as a result of overpumping, causing the ground above them to subside.   True  False
12 .		Earth's largest known aquifer, the High Plains Aquifer, would require about 1000 years to recover from historic pumping if all groundwater mining stopped today.   True  False
