8.E.1.1 Review

The well is too shallow and is tapped into the shallow ocean currents.

The well is too deep and is hitting an underground saltwater aquifer.

The water in the aquifer is being used faster than it is naturally replenished and the ocean water is encroaching upon it.

An increase in droughts is slowly reducing freshwater reservoirs.

Due to an increase in Earth’s temperature, evaporation rates continue to increase reducing liquid water on the surface.

Earth’s freshwater continues to become more polluted, reducing the supply of freshwater safe for humans to consume.

Distilling ocean water would not produce enough freshwater to supply all areas where freshwater is lacking.

Distilling ocean water is a simple process, but current technology does not exist to produce such a large supply of freshwater.

Distilling ocean water is too expensive of a process to produce enough freshwater supply to all areas where freshwater is lacking.

Distilling ocean water involves the use of hazardous chemicals, and the water would be contaminated after the process was complete.

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

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
