The 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 transpiration?

Back

Transpiration is the process by which plants release water vapor into the air through small openings in their leaves.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually 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 or dew.

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, usually from rain or melted snow, that moves across the ground and returns to rivers, lakes, and oceans.

Front

What is accumulation in the water cycle?

Back

Accumulation refers to the collection of water in bodies of water like rivers, lakes, and oceans after precipitation.

Front

What is sublimation?

Back

Sublimation is the process where ice or snow changes directly into water vapor without first becoming liquid.

Front

How does the sun affect 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.
