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

Define evaporation.

Back

Evaporation is the process by which water changes from a liquid to a gas or vapor, usually due to heat.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

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

Explain the process of convection in the water cycle.

Back

Convection is the movement within a fluid where warmer, less dense water rises and cooler, denser water sinks, helping to transfer heat and moisture.

Front

What role does transpiration play in the water cycle?

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor into the atmosphere.

Front

What is the sequence of processes in the water cycle?

Back

The correct sequence is: Evaporation, Condensation, Precipitation.

Front

How does evaporation contribute to the water cycle?

Back

Evaporation generates most of the water vapor in the atmosphere, which is essential for cloud formation and precipitation.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes and rivers, while transpiration is the release of water vapor from plants.

Front

What is the significance of clouds in the water cycle?

Back

Clouds are formed during condensation and are crucial for precipitation, which returns water to the Earth's surface.
