Water and its Importance

What are some unique qualities of water?

• High heat capacity, ability to dissolve and transport substances, transparency to light, and expansion when freezing

• Low heat capacity, inability to dissolve and transport substances, opacity to light, and contraction when freezing

• High heat capacity, inability to dissolve and transport substances, transparency to light, and contraction when freezing

Match each water cycle process in the list below with a number from

Figure 2.20.

• 6

• evaporation

• 7

• precipitation

• 1

• transpiration

• 5

• surface runoff

• 4

• infiltration

If more wells were built and a large amount of water was pumped from them, what might happen to the water level in the river?

• The water level could lower

• The water level could rise

• There would be no effect

• It's impossible to predict

Fertilizers sprayed on a field near point A were found in the well water. They most likely got there through:

• Evaporation and precipitation

• Transpiration

• Infiltration and groundwater flow

• They flowed there through the river.
