4.8B Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process where liquid water is heated by the sun and turns into water vapor, rising into the atmosphere.

Front

What is condensation?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds or dew.

Front

What is precipitation?

Back

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

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, helping to move water from the surface to the atmosphere.

Front

What is transpiration?

Back

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

Front

How does dew form?

Back

Dew forms when water vapor in the air cools and condenses into tiny droplets on surfaces, usually during the night.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from any surface, while transpiration specifically refers to water vapor released by plants.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining the Earth's water supply, supporting ecosystems, and regulating climate.

Front

What happens during the process of freezing?

Back

Freezing is the process where liquid water turns into ice when temperatures drop below 0°C (32°F).
