Water: Porosity, permeability, and aquifers

What definition BEST describes a watershed?

• An area where water infiltrates the soil

• An area where aquatic plants and animals thrive

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

What is an aquifer?

• a body of permeable rock which can contain or transmit groundwater.

• a well in which water is under pressure especially : one in which the water flows to the surface naturally.

• confining layer

• solid rock underlying loose deposits such as soil or alluvium.
