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 where water changes from a liquid to a gas, usually 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.

Front

What is precipitation?

Back

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

Front

What is surface runoff?

Back

Surface runoff is the flow of water that occurs when excess rainwater, meltwater, or other sources flows over the Earth's surface.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants' roots, moves through plants, and is released as vapor through pores in leaves.

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle by heating water in oceans, rivers, and lakes.

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 happens during the process of accumulation?

Back

Accumulation is the process where water collects in bodies like rivers, lakes, and oceans after precipitation.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining ecosystems, providing fresh water, and regulating climate.
