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 happens during evaporation?

Back

Evaporation is the process where liquid water turns into water vapor (gas) when it is heated.

Front

What is condensation?

Back

Condensation is the process where water vapor (gas) cools down and turns back into liquid water.

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 water vapor?

Back

Water vapor is water in its gaseous state, which is invisible and present in the air.

Front

How does temperature affect evaporation?

Back

Evaporation happens faster at higher temperatures because heat provides energy for water molecules to escape into the air.

Front

Where does the water we drink come from?

Back

Most of the water we drink has been on Earth for millions of years, cycling through the water cycle.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the heat energy needed for evaporation to occur, driving the water cycle.

Front

What is the difference between liquid water and water vapor?

Back

Liquid water is the form we see in rivers and lakes, while water vapor is the invisible gas that is part of the air.

Front

What happens to water droplets on a cold surface?

Back

Water droplets form on a cold surface when water vapor in the air cools down and condenses into liquid water.
