Water Cycle Flashcard

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 such as evaporation, condensation, precipitation, and runoff.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water is transformed into water vapor, usually due to heat from the sun.

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

What is runoff?

Back

Runoff is the flow of water, usually from rain or melted snow, that moves across the land and eventually returns to bodies of water like rivers, lakes, and oceans.

Front

How do clouds form in the water cycle?

Back

Clouds form when water vapor in the air cools and condenses into tiny water droplets or ice crystals.

Front

What role does the sun play 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 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 into the atmosphere.

Front

What is the significance of the water cycle for ecosystems?

Back

The water cycle is crucial for maintaining ecosystems as it distributes water, supports plant growth, and regulates climate.

Front

What happens during the process of infiltration?

Back

Infiltration is the process by which water on the ground surface enters the soil, replenishing groundwater supplies.
