Question

which statements about humidity are true? check all that apply.
humidity is the measure of the amount of water vapor in the air.
warm air holds less water vapor than cold air.
warm areas promote less evaporation.
areas with a large amount of surface water have high humidity levels.
warm tropical areas have very humid air.

Explanation:

• Humidity is indeed the measure of the amount of water vapor in the air.
• Warm air can hold more water vapor than cold air (so the statement "Warm air holds less water vapor than cold air" is false).
• Warm areas promote more evaporation (so the statement "Warm areas promote less evaporation" is false).
• Areas with a large amount of surface water have more water available to evaporate, leading to high humidity levels.
• Warm tropical areas have high temperatures which allow for more evaporation and thus very humid air.

Answer:

Humidity is the measure of the amount of water vapor in the air.
Areas with a large amount of surface water have high humidity levels.
Warm tropical areas have very humid air.
