The 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 by which water changes from a liquid to a gas or vapor, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

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 is transpiration?

Back

Transpiration is the process by which water vapor is released from plants into the atmosphere.

Front

What is run-off?

Back

Run-off is the water that flows over the ground surface and returns to rivers, lakes, and oceans after rainfall.

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes and rivers, while transpiration is the release of water vapor from plants.

Front

What happens during the condensation stage of the water cycle?

Back

During condensation, water vapor cools and forms tiny droplets that gather to create clouds.

Front

What is the significance of the water cycle for the environment?

Back

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