Water Distribution

The main source of Earth's water is the ocean, which holds about 97% of all water on Earth.

Only about 3% of Earth's water is freshwater.

False. Most of Earth's freshwater is stored in glaciers and ice caps.

The ocean holds most (97%) of Earth's water and is a key component in the water cycle.

True. Approximately 97% of Earth's water is salt water.

Only a small fraction of freshwater is available for human use, as most is trapped in glaciers or underground.

Groundwater is water that is stored underground in soil and rock layers.

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

When water evaporates, it changes from a liquid to a gas (water vapor) and enters the atmosphere.

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.
