Earth Science- Ch. 2 test Review

Where is the majority of Earth’s water found?

• In rivers

• In groundwater

• In oceans

• In the atmosphere

The unique qualities of water that make it critical to the functioning of Earth’s systems include

• the fact that frozen water is denser than liquid water.

• water’s ability to store large quantities of heat.

• the fact that water exists on Earth’s surface only in liquid form.

• its presence primarily as freshwater on Earth’s surface.

Most water vapor enters the atmosphere by the processes of

• convection and radiation.

• condensation and precipitation.

• evaporation and transpiration.

• erosion and conduction.

Freshwater enters a surface water body such as a lake via

• precipitation.

• groundwater flow.

• runoff.

• all of the above.

In Figure 2.1 the line labeled B is called the

• water table.

• watershed.

• saturated zone.

• unsaturated zone.

Look carefully at Figure 2.1. If more wells were built and a great deal of water was pumped from them, what might happen to the water level in the river?

• The water level could rise.

• The water level could lower.

• The wells would not affect the river.

• It is impossible to predict what could happen.

Look carefully at Figure 2.1. Fertilizers sprayed on a field near point A are found in the well water. The fertilizer most likely got into the water through

• evaporation and precipitation.

• infiltration and groundwater flow.

• transpiration and advection

• flowing through the river

Which of the following materials is likely to be most permeable?

• pure clay

• pure sand

• a mixture of sand and clay

• plastic sheeting

Figure 2.2 shows that the worst drought conditions were in the ____ region of the US.

• South central

• Northeast

• Northwest

• Midwest

Look carefully at Figures 2.2 and 2.3. Which region of the US experienced the most extensive drought conditions in both 2008 and 2011?

• South central

• Western

• Eastern

• North central
