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.

What happens during evaporation?

Back

Evaporation is the process where liquid water turns into water vapor and rises into the atmosphere, usually due to heat from the sun.

What is condensation?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming tiny droplets that can create clouds.

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.

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the air through tiny openings in their leaves.

What role do clouds play in the water cycle?

Back

Clouds are formed from condensed water vapor and are essential for precipitation, returning water to the Earth's surface.

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

Back

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

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.

How does temperature affect the water cycle?

Back

Higher temperatures increase evaporation rates, leading to more water vapor in the atmosphere, while lower temperatures can lead to condensation and precipitation.

What is accumulation in the water cycle?

Back

Accumulation refers to the collection of water in bodies like rivers, lakes, and oceans, where it can eventually evaporate again.
