• the revolution of earth on its axis
• differences in density of ocean water
• the rotation of earth on its axis

Which is the most common contamination source for freshwater resources?

• runoff

• digging wells

• melting of glaciers

• lightning

A community decides to upgrade its water purification and management systems. What lasting impact could this have on available freshwater?

• It could cause a decrease in water demand (how much water people use).

• It could cause an increase in waterborne diseases.

• It could cause an increase in the freshwater supply due to more efficient equipment.
