Which term describes the amount of water vapor in the air?

• A. Humidity
• B. Drought
• C. Precipitation
• D. Atmosphere

Answer: (A)

Humidity is the amount of water vapor in the air. It shows how moist the air is. When there’s a lot of water vapor, humidity is high; when there’s less, humidity is low. Relative humidity expresses this as a percentage of the maximum water vapor the air could hold at the current temperature. Warm air can hold more moisture, so humidity can feel different as temperature changes even if the actual amount of water vapor isn’t the same. Drought describes a long period with little or no rainfall, precipitation means water that falls from the sky, and the atmosphere is the layer of gases surrounding Earth. Since humidity specifically refers to how much water vapor is in the air, it’s the right term.
