Why is water from an aquifer more likely to be cleaner than water from other sources?

• because it forms where fresh and salt water meet

• because it receives water directly from precipitation

• because it rises to the surface near the ocean

• because pollutants are filtered by rock and soil deep within Earth

Which best describes the characteristics of a river basin?

• the land drained by a river and its tributaries

• the land formed when rivers create estuaries and marshes

• the land at the mouth of a river where water flows into the ocean

• the land formed as a result of a river flooding

Which best describes the process of evapotranspiration in the water cycle?

• Water from the ocean enters the atmosphere as water vapor

• Water on the surface of Earth enters the groundwater supply

• Water vapor in the atmosphere returns to the surface of Earth as liquid water

• Water on the surface of Earth and water lost by plants enters the atmosphere as water vapor

A water table well and another well going into an aquifer are shown in the diagram. During a drought, the water table dries while the aquifer remains nearly full. Which best explains this?

• During the drought, the water table increases, but the water level in the confined aquifer increases.

• During the drought, the water table falls, but the confined aquifer is mostly isolated from the drought conditions and remains unaffected.

• During the drought, the water table remains constant, but the confined aquifer keeps its water level because of other sources of water.

A local farm experiences significant drought over a 2-year period. A temporary solution for the lack of water is to dig another well closer to the fields to water crops. Two years before, in a similar situation, the water table was reached at 15 feet below the ground. Which is necessary for the well to supply water to the crops?

• The well needs to be dug to 13.5 feet.

• It is not necessary to find the water table when digging a well.

• The well should be dug to more than 15 feet to find the water table.

Sea otters consume sea urchins, which in turn thrive in kelp forests off the coast of California. These underwater forests depend on cold water. Which would yield the most stable ecosystem for sea otters?
