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 water changes from a liquid to a gas (water vapor) due to heat from the sun.

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 heat energy needed for evaporation, driving the water cycle.

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 surfaces like lakes, while transpiration is the release of water vapor from plants.

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, which can be accessed through wells.

Front

What is the importance of the water cycle?

Back

The water cycle is essential for replenishing freshwater sources, supporting ecosystems, and regulating climate.
