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 (water vapor) 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 droplets.

Front

What is precipitation?

Back

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

Front

What is runoff?

Back

Runoff is the flow of water from rain or melting snow that moves over the ground and eventually flows into rivers, lakes, and oceans.

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, causing water from oceans, lakes, and rivers to turn into vapor.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor into the atmosphere.

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 is the significance of clouds in the water cycle?

Back

Clouds are formed from condensed water vapor and play a crucial role in transporting water in the atmosphere and returning it to the Earth as precipitation.

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).
