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, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air 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, 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 factors increase evaporation?

Back

Factors that increase evaporation include higher temperatures, increased wind speed, and lower humidity.

Front

How does temperature affect the water cycle?

Back

Higher temperatures increase evaporation rates, while lower temperatures can lead to condensation and precipitation.

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.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.

Front

How do human activities impact the water cycle?

Back

Human activities, such as deforestation and urbanization, can alter natural water flow, increase runoff, and affect local precipitation patterns.
