Chapter 14 Review

The ability of a material to transmit water through interconnected pores is called

• capacity
• competence
• permeability
• porosity

How much of the earth's water is freshwater?

• 50 %
• 3 %
• 97 %
• 93 %

Suppose there is a drought in this area. The level of the river drops because of it.
What else could happen here?

• The river will immediately rise again.
• The water table will rise. 
• The water table will fall. 
• A new aquifer will form.

Why is such a small amount of freshwater available for humans to readily use?

• Majority of freshwater is mixed in with the ocean water
• Most of fresh water is frozen in glaciers and polar ice caps
  
• Most of freshwater found in the gas form in the atmosphere
• Most of freshwater is liquid in lakes, rivers , & aquifers

An area of land that drains into a body of water.

• mouth
• point-source pollution
• watershed
• headwaters

A _________________ source of pollution is a water pollution source that happens in a specific area, such as a spot where chemicals are being directly dumped in the water.

• point

• nonpoint

• aquifer

• gravity

A __________________ source of water pollution is water pollution over a larger area, such as roadways, agricultural areas, and industrial sites.

• point

• nonpoint

• aquifer

• gravity

The process of the hydrologic cycle by which water percolates through permeable soil and rock is called ? .

• percolation

• infiltration

• permeation

• hydrolocation

The pumping of freshwater increases along a coastal area. What is a likely result of over-pumping?

• A decrease in salt concentration in inlet waterways

• Destruction of estuaries because of an increase in sea levels

• The loss of water resources in estuaries

• An intrusion of salt water into aquifers

Impermeable materials...

• have an abundance of pores.
• let water in.
• have little to no pores.
