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, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

What is runoff?

Back

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

Front

What percentage of Earth's water is saltwater?

Back

About 97% of Earth's water is saltwater, primarily found in oceans.

Front

What is groundwater?

Back

Groundwater is water that is stored underground in aquifers and is a significant source of freshwater.

Front

How does gravity affect the water cycle?

Back

Gravity pulls water down from clouds as precipitation and drives runoff towards oceans and lakes.

Front

What role do plants play in the water cycle?

Back

Plants contribute to the water cycle through transpiration, where they release water vapor into the atmosphere.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining ecosystems, regulating climate, and providing freshwater for all living organisms.
