Water Cycle, Dew Point & Relative Humidity

Front

What is evaporation?

Back

Evaporation is the process where liquid water molecules gain enough energy to transform into gas.

Front

What is condensation?

Back

Condensation is the process where gas water molecules lose heat energy and change back into liquid water.

Front

What happens to water vapor as air rises in the atmosphere?

Back

As air rises, it cools and the water vapor condenses into liquid or solid state, forming clouds.

Front

When does dew form?

Back

Dew forms when warm humid air contacts cold ground, causing water vapor to condense into liquid droplets.

Front

What is relative humidity?

Back

Relative humidity is the amount of water vapor in the air at the current temperature related to the total amount it could hold at that temperature.

Front

What is the role of temperature in the water cycle?

Back

Temperature affects the rate of evaporation and condensation, influencing the water cycle's processes.

Front

What is the dew point?

Back

The dew point is the temperature at which air becomes saturated with moisture and water vapor begins to condense.

Front

How does humidity affect weather?

Back

High humidity can lead to cloud formation and precipitation, while low humidity can result in clear skies.

Front

What is the difference between absolute humidity and relative humidity?

Back

Absolute humidity measures the actual amount of water vapor in the air, while relative humidity compares that amount to the maximum it could hold at a given temperature.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the air from their leaves.
