The Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates into the atmosphere, condenses into clouds, and precipitates back to Earth.

Front

What is the largest source of water on Earth?

Back

The largest source of water on Earth is saltwater found in oceans, not freshwater.

Front

Define evaporation in the context of the water cycle.

Back

Evaporation is the process by which water changes from a liquid state to a gaseous state (water vapor).

Front

What is condensation in the water cycle?

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 clouds to the Earth's surface.

Front

What is run-off in the water cycle?

Back

Run-off is the movement of water, usually from precipitation, that travels over the ground and eventually flows into rivers, lakes, and oceans.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed during the condensation phase of the water cycle and are essential for precipitation.

Front

What is the difference between fresh water and saltwater?

Back

Fresh water has a low concentration of salts and is found in rivers, lakes, and glaciers, while saltwater has a high concentration of salts and is found in oceans.

Front

How does temperature affect evaporation rates?

Back

Higher temperatures increase the rate of evaporation, as more water molecules have enough energy to escape into the air.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor through their leaves.
