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 evaporation?

Back

Evaporation is the process where water changes from a liquid to a gas, usually caused by heat from the sun.

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 clouds to the Earth's surface, including rain, snow, sleet, and 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 causes evaporation to happen faster?

Back

Evaporation happens faster on warm, sunny days because the sun's heat increases the temperature of the water.

Front

What are clouds made of?

Back

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

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 happens during precipitation?

Back

During precipitation, water falls from the atmosphere to the Earth's surface in various forms like rain, snow, or sleet.

Front

What is the difference between rain and snow?

Back

Rain is liquid water that falls when temperatures are warm, while snow is frozen water that falls when temperatures are cold.
