The Water Cycle and Human Impact Flashcard

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves through the environment, including evaporation, condensation, precipitation, and runoff.

Front

What happens during evaporation in the water cycle?

Back

Evaporation is the process where water changes from a liquid to a gas (water vapor) due to heat from the sun.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed when water vapor condenses in the atmosphere, and they are crucial for precipitation.

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.

Front

How do human activities impact the water cycle?

Back

Human activities can alter the local balance of the water cycle by changing land use, increasing evaporation, and affecting precipitation patterns.

Front

What is condensation in the water cycle?

Back

Condensation is the process where 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 clouds to the Earth's surface.

Front

How do clouds affect Earth's temperature?

Back

Clouds can both cool and warm the Earth by reflecting sunlight and trapping heat.

Front

What is the effect of pollution on water quality?

Back

Pollution can overwhelm natural abilities to remove contaminants, leading to decreased water quality.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the atmosphere from their leaves.
