What term describes the amount of moisture in the air?

• A. Humidity
• B. Condensation
• C. Precipitation
• D. Dew Point

Answer: (A)

The main idea is how we describe moisture in the air. Humidity is the measure of how much water vapor is present in the air. It's often talked about as relative humidity, a percent that indicates how close the air is to being saturated at the current temperature. When humidity is high, the air feels more muggy; when it's low, the air feels drier. Condensation describes the process of water vapor turning into liquid water; precipitation is when liquid or solid water falls from the sky as rain, snow, etc.; dew point is the temperature at which air becomes saturated and water vapor starts to condense. So humidity specifically names the amount of moisture in the air, while the other terms describe what happens to that moisture or the temperature at which saturation occurs.
