Earth's water distribution
Most of Earth's water is salt water in oceans and seas, and much of the freshwater is locked in ice or underground. Only a small portion is readily available in rivers and lakes.
Usable freshwater
Usable freshwater
The freshwater readily accessible for drinking and use in rivers, lakes, and some above ground sources.

Study Notes
Earth's Water Distribution
- Most of Earth (70%) is water, but much of it is saltwater in oceans and seas, making it undrinkable.
- Most freshwater is either ice or underground, making it hard to access readily.
- Only a small portion of water is in rivers and lakes, readily accessible for human use.
Water Availability
- Water exists in the atmosphere as well, forming clouds and precipitation (rain and snow).
- These forms of water are crucial for plant life and human consumption.
- The provided text emphasizes the importance of conserving water resources.
The Water Cycle
- Earth's water supply is ancient; it has always been present in various forms and locations.
- Water continuously moves through a cyclic process, the water cycle.
- Solar radiation heats water sources, causing some water to evaporate and rise into the atmosphere.
- As the air cools, the water vapor condenses into clouds.
- Clouds release water as rain or snow based on temperature.
- Precipitation falls on land, some running into rivers and eventually back to the sea, while others seep into the ground.
