Water Cycle CFA

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What role does the sun play in the water cycle?

Back

The sun provides energy that causes water to evaporate from oceans, lakes, and rivers, initiating the water cycle.

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 clouds.

Front

What is precipitation?

Back

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

Front

Why do oceans contribute most to evaporation?

Back

Oceans expose the most water to the sun's energy, which increases the rate of evaporation.

Front

What happens to water vapor in the atmosphere?

Back

Water vapor rises, cools, and condenses to form clouds, which can lead to precipitation.

Front

What is run-off in the water cycle?

Back

Run-off is the flow of water that occurs when excess water from rain or melting snow flows over the ground and returns to oceans, rivers, and lakes.

Front

How do plants contribute to the water cycle?

Back

Plants absorb water from the soil and release water vapor into the atmosphere through a process called transpiration.

Front

What is the difference between evaporation and transpiration?

Back

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