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.
