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 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 droplets.

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 sublimation?

Back

Sublimation is the process where a solid (like snow or ice) changes directly into a gas (water vapor) without becoming a liquid first.

Front

What is transpiration?

Back

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

Front

What is the role of the sun in 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 happens during freezing?

Back

Freezing is the process where liquid water turns into solid ice, releasing energy in the form of heat.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at any temperature and only at the surface of the liquid, while boiling occurs at a specific temperature throughout the liquid.

Front

What is the significance of the water cycle for the environment?

Back

The water cycle is essential for maintaining ecosystems, providing fresh water, regulating climate, and supporting plant and animal life.
