12/18 5 Little Questions - 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 such as evaporation, condensation, precipitation, and runoff.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) due to heat.

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, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is transpiration?

Back

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

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and returns to bodies of water like rivers, lakes, and oceans.

Front

How does the sun influence the water cycle?

Back

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

Front

What role do clouds play in the water cycle?

Back

Clouds are formed by condensation and are essential for precipitation, as they hold water vapor that eventually falls as rain or snow.

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 is the significance of the water cycle for ecosystems?

Back

The water cycle is crucial for maintaining ecosystems, providing fresh water for plants, animals, and humans, and regulating climate.
