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.

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the air as a waste product.

Front

What is precipitation?

Back

Precipitation is the part of the water cycle when clouds get heavy and can no longer hold the liquid water, causing it to fall to the Earth as rain, snow, sleet, or hail.

Front

What role does the sun play in the water cycle?

Back

The sun provides heat energy for evaporation, which turns liquid water into water vapor.

Front

What happens during condensation?

Back

During condensation, water vapor in the air cools down and turns back into liquid water, forming clouds.

Front

What is evaporation?

Back

Evaporation is the process where liquid water is heated by the sun and turns into water vapor.

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 is the difference between fresh water and salt water?

Back

Fresh water is water that has low concentrations of dissolved salts, while salt water contains a high concentration of salts, primarily found in oceans.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining ecosystems, providing fresh water for drinking, agriculture, and supporting all forms of life.

Front

What is dew?

Back

Dew is moisture that forms on surfaces when water vapor condenses into liquid water, usually during cooler temperatures at night.
