Water Cycle, Dew Point & Relative Humidity

Front

What is the dew point?

Back

The dew point is the temperature at which 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 causes water vapor in the air to form clouds?

Back

Water vapor in the air forms clouds when the air rises in the atmosphere, cools, and the water vapor condenses to a liquid or solid state.

Front

When does dew form?

Back

Dew forms when warm humid air contacts cold ground.

Front

What is condensation?

Back

Condensation happens when gas water molecules lose heat energy and stick to an object as liquid.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor.

Front

What is the role of the sun in the water cycle?

Back

The sun provides energy that drives the water cycle, causing evaporation and influencing weather patterns.

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

As temperature increases, the air can hold more water vapor, which can lead to lower relative humidity if the amount of water vapor remains constant.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.
