fill in the blank with the appropriate term.

1. most fresh water on earth exists in the ________ state.
2. the amount of time a molecule such as water stays in a reservoir is its ________ time

Explanation:

Question 6

• Aquifers are natural underground water reservoirs, springs are natural water sources from underground, while aqueducts are artificial structures to transport water. So artificial sources of water include aqueducts.

In the U.S., the largest use of water is for cooling in power plants and industrial processes, more than for drinking, bathing, or farming.

1. Sublimation is the process of a solid changing directly to a gas, so match with d. sublimation.
2. Transpiration is the process of plants releasing water vapor through leaves, so match with f. transpiration.
3. Evaporation is liquid to gas, so match with e. evaporation.
4. Fresh water makes up about 3% of Earth's water, so match with b. fresh water.
5. Precipitation is water falling from clouds, so match with g. precipitation.
6. A reservoir is a storage location for water, so match with a. reservoir.
7. Condensation is gas to liquid, so match with c. condensation.

Answer:

b. aqueducts
