How much of Earth's total water supply is usable freshwater?

• less than 1%

• less than 25%

• greater than 50%

• greater than 75%

Why is water from an aquifer cleaner than from other sources?

• it forms where fresh and salt water meet

• it receives water directly from rain

• it rises to the surface near the ocean

• pollutants are filtered by rock and soil deep within Earth

Which accurately describes a river basin?

• land formed when rivers create estuaries

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

• land drained by a river and its tributaries

• land formed as a result of river flooding

How could urban sprawl affect water availability?

• deeper wells need to be accessed due to population growth

• changing the shape of the land changes the watershed that supplies river systems

• building a neighborhood increases water levels/supply

• as water supplies increase, the demand for water will decrease

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

• water moves slowly through an aquifer, so it will take a long time to clean itself

• chemicals could cause the water to taste bad

How could you compare river basins and watersheds?

• a river basin has many watersheds that all drain to it

• a watershed has many river basins that all drain to it

What will happen to a water table if well pumping happens during a long period of drought?

• the level of the water table will rise

• the level of the water table will fall

Primary source of freshwater?

• groundwater

• oceans

• lakes

• glaciers and caps

Aquifers must have . . . .

• rocks that are permeable and contain few pores

• rock that are permeable and contain many pores

• rock that are impermeable and contain few pores

• rock that are impermeable and contain many pores
