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 evaporation?

Back

Evaporation is the process where water heats up and changes from a liquid to a gas (water vapor).

Front

What is condensation?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

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

Front

What is runoff?

Back

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

Front

What are clouds made of?

Back

Clouds are made of tiny water droplets or ice crystals that form when water vapor condenses.

Front

What is water vapor?

Back

Water vapor is the gaseous form of water that is present in the air.

Front

How does the sun affect the water cycle?

Back

The sun provides the energy needed for evaporation, which drives the water cycle.

Front

What happens during the process of transpiration?

Back

Transpiration is the process where plants release water vapor into the air from their leaves.

Front

What role do oceans play in the water cycle?

Back

Oceans are the largest source of water for evaporation, contributing significantly to the water cycle.
