Precipitation that falls on land enters the ground through the process of ___________ and becomes groundwater.

• infiltration

• drawdown

• permeability

• water vapor

The area in an aquifer, below the water table, in which relatively all pores and fractures are filled with water.

• zone of aeration

• zone of saturation

• infiltration

• groundwater

This is the comparatively dry soil or rock located between the ground surface and the top of the water table. The ___________ is not saturated with water because its pores are filled partly by air and partly by water.

• zone of aeration

• zone of saturation

• infiltration

• groundwater

The ability of a material to let water pass through it is called _______________

• drawdown

• aquifer

• permeability

• porosity

The percentage of pore space in a material is called ____________.

• permeability

• groundwater

• infiltration

• porosity

A body of permeable rock which can contain or transmit groundwater.

• aquifer

• porosity

• groundwater

• well

The level below which the ground is saturated with water

• precipitation

• water level

• infiltration

• well

Water flows under natural pressure without pumping. It is dug or drilled wherever a gently dipping, permeable rock layer (such as sandstone) receives water along its outcrop at a level higher than the level of the surface of the ground at the well site.

• ordinary well

• subsidence

• artesian well

• springs

A section of impermeable rock forces groundwater to emerge onto the surface of the Earth.

• springs

• hot springs

• geysers

• well

The land area drained by a stream system

• groundwater

• watershed

• water cycle

• water table
