What is point B?

the water stored in the ground

Which statement best describes what happens at the site of a divide?

a river or stream flowing into a larger river or lake

Which source contains most of Earth’s fresh water?

the water that flows over the ground surface

a well in which water reaches the surface due to the natural pressure of an aquifer

Where is most of Earth’s usable fresh water found?

Which phrases describe both lakes and ponds?

the top of the saturated zone

Which zone is a boundary between water and a mixture of moisture and air?

Which statements about wells are true?
