Desalination is

• removing salt from water
• removing oil from water
• removing toxic chemicals from water
• adding salt to water

Water that collects in spaces and cracks in rocks and soil underground.

• well
• aquifer
• groundwater
• irrigation

Rainwater that flows over land without sinking into the soil.

• runoff
• spring
• groundwater
• aqueduct

A hole dug or drilled into the ground to provide a supply of water.

• watershed
• desalination
• groundwater
• well

As rock becomes more porous...

• The more water it can hold

• The less water it can hold

• The porosity of rock does not determine how much water it can hold

What would be the best definition of permeability?

• Percentage of the total volume of a rock or sediment that consists of open spaces

• The ability of a rock or sediment to let fluids pass through open spaces or pores

• The inability of a rock or sediment to let fluids pass through open spaces or pores

• The level below which the ground is saturated with water

The size of an aquifer’s recharge zone is affected by the _________________ of the surface above the aquifer.

• Permeability

• Porosity

• Water table

• Desalinization

Which of the following is NOT a part of the hydrologic cycle?

• Photosynthesis

• Evaporation

• Condensation

• Precipitation

Transpiration is the way plants

• Return large amounts of water to the atmosphere

• Absorb water from the atmosphere

• Absorb water from the ground

• Return large amounts of water from the atmosphere to the ground
