Study Notes
Earth's Water Composition
- Water covers 71% of Earth's surface.
- 96.5% of Earth's water is salt water, which contains various salts, mainly sodium chloride.
- Only 3.5% of Earth's water is freshwater that is suitable for drinking.
Distribution of Freshwater
- 68% of freshwater is trapped in ice and glaciers.
- A third of freshwater is in the ground, known as groundwater.
- The remaining 2% of freshwater is in rivers, lakes, and streams.
- A very small amount of freshwater exists as water vapor in the atmosphere, forming clouds.
Interesting Facts
- If all the water on Earth were combined, it would form a massive ball 860 miles wide.
- The human body is comprised mostly of water.
