Water Cycle Practice

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 liquid water turns into water vapor, usually when heated.

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 transpiration?

Back

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

Front

What role does thermal energy play in the water cycle?

Back

Thermal energy from the sun drives the water cycle by providing the heat necessary for evaporation.

Front

How does temperature affect evaporation?

Back

Warm water evaporates quicker than cold water because higher temperatures provide more energy for water molecules to escape into the air.

Front

What happens during the process of precipitation?

Back

During precipitation, water droplets in clouds combine and grow heavy enough to fall to the ground.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of liquid turning into vapor, while condensation is the process of vapor turning back into liquid.

Front

What is runoff in the water cycle?

Back

Runoff is the flow of water, usually from rain, that moves across the ground and returns to bodies of water like rivers, lakes, and oceans.
