Water Cycle & Distribution of Water on Earth

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 are the main processes of the water cycle?

Back

The main processes of the water cycle are evaporation, condensation, precipitation, and collection.

Front

Why are oceans important in the water cycle?

Back

Oceans are important because they are large bodies of salt water that provide a significant source of freshwater through evaporation.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) 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 that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What percentage of Earth's water is freshwater?

Back

Only 2.5% of Earth's water is freshwater.

Front

Where is most of Earth's freshwater found?

Back

Most of Earth's freshwater (about 78%) is found in glaciers and ice caps.

Front

What role does the Sun play in the water cycle?

Back

The Sun provides the energy needed for evaporation, driving the water cycle.

Front

What is the difference between saltwater and freshwater?

Back

Saltwater contains a high concentration of salt, primarily found in oceans, while freshwater has low salt content and is found in rivers, lakes, and glaciers.
