Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves through the environment, including 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 droplets.

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

What is runoff?

Back

Runoff is the water that flows over the ground surface and returns to rivers, lakes, and oceans.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed by condensed water vapor and are essential for precipitation, as they release water back to the Earth's surface.

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

How does temperature affect evaporation?

Back

Higher temperatures increase the rate of evaporation, as heat provides energy for water molecules to escape into the air.

Front

What is the difference between surface water and groundwater?

Back

Surface water is found in rivers, lakes, and oceans, while groundwater is water that is stored underground in soil and rock layers.

Front

What is the significance of the water cycle for ecosystems?

Back

The water cycle is crucial for maintaining ecosystems, as it provides fresh water for plants, animals, and humans.
