Exam 9: Water Resources

A water budget is derived from measuring system inputs of precipitation and system outputs of evapotranspiration and runoff.

Sea-level change caused by glacial activity is known as glacioeustasy.

Which of the following is not a freshwater wetland?

The High Plains aquifer

Approximately what percent of the U.S. population derives a portion of its fresh water from groundwater sources?

Precipitation intercepted by plants may eventually reach the Earth's surface through stem flow.

Precipitation is the main source of groundwater, percolating downward as gravitational water from the soil moisture zone.

There is more groundwater than there is water in freshwater lakes, the atmosphere, and rivers and streams combined.

The largest sector of daily water withdrawals in the water budget for the United States is presently that taken for agricultural purposes.

Because groundwater can be recharged through percolation, overconsumption is not currently a concern.

Soil and rock that are less than saturated through which gravitational water moves is known as the zone of aeration.

Both overconsumption and pollution pose issues for water resource management.

The permanent removal of water from its source is known as consumptive use.

The general term for the lowering of water table of an aquifer through pumping is the potentiometric surface.

Which of the following is true of the distribution of land and water on Earth?

Warming temperatures can lead to both increases and decreases in lake levels.
