Water Cycle, Dew Point & Relative Humidity

Front

What is the dew point?

Back

The dew point is the temperature air cools down to reach condensation (or turn into a liquid).

Front

What is humidity?

Back

Humidity is the amount of water vapor in the air.

Front

What process occurs when liquid water molecules transform into a gas?

Back

Evaporation.

Front

What is the correct order of the water cycle?

Back

Radiation, evaporation, condensation, precipitation.

Front

What happens when the dew point temperature and the actual air temperature are similar?

Back

Clouds and precipitation are more likely.

Front

What is condensation?

Back

Condensation is the process where water vapor cools and changes back into liquid water.

Front

What is evaporation?

Back

Evaporation is the process where liquid water is heated and changes into water vapor.

Front

What role does radiation play in the water cycle?

Back

Radiation from the sun provides the energy needed for evaporation.

Front

What is relative humidity?

Back

Relative humidity is the percentage of water vapor present in the air compared to the maximum amount the air can hold at that temperature.

Front

How does temperature affect humidity?

Back

Warmer air can hold more water vapor than cooler air, so as temperature increases, relative humidity can decrease if no additional moisture is added.
