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

How can urban sprawl affect water availability?

• The demand for water will decrease, and water supplies will increase.

• Deeper wells will need to be accessed to accommodate the population growth.

• Changing the shape of the land changes the watershed that supplies river systems.

• Building neighborhoods increases the water level of reservoirs supplying water to the region.

Why is polluting an aquifer more dangerous than polluting other bodies of water?

• Chemicals may be visible in larger bodies of water, while those in aquifers may be invisible.

• Water moves very slowly through an aquifer, and it takes a long time to clean itself.

• Water quickly leaves the aquifer and affects organisms living in the ocean.

• Chemicals in the water may cause the water to have a bad flavor.

Which accurately compares river basins and watersheds?

• A river basin consists of many watersheds that all drain into it.

• A watershed consists of many river basins that all drain into it.

• River basin and watershed are terms that have the same meaning.

• Some areas are drained by river basins and others are drained by watersheds.

Which is the primary source of freshwater in the hydrosphere?

• glaciers and ice caps

• groundwater

• oceans

• lakes

Which processes would most likely cause a local river basin to dry up?

• increased precipitation and decreased evaporation

• decreased precipitation and increased evaporation

• decreased precipitation and decreased evaporation

Ocean water can be distilled to remove the salt and other dissolved substances, producing pure water. Which best describes the feasibility of distilling ocean water as a means of supplying freshwater to people in areas where the supply of freshwater is lacking?

• 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.
