Study Notes
Water Surrounding the Earth
- Earth is often called the "Water Planet" or "Blue Planet" due to the abundant water.
- 71% of Earth's surface is covered by water.
- 97% of the Earth's water is saltwater found in oceans and seas.
- 2% of Earth's water is glacier ice.
- Less than 1% of Earth's water is freshwater found in rivers and lakes.
- Major water reservoirs include the Pacific, Atlantic, Indian, and Arctic Oceans.
The Water Cycle
- Earth receives most fresh water through rainfall.
- Fresh water also comes from numerous springs and rivers.
- Water constantly cycles, with no beginning or end.
- The sun's energy causes evaporation of water from oceans.
- Evaporated water forms clouds through condensation.
- Condensed water falls as precipitation (rain, snow, hail).
- Precipitation flows into rivers, infiltrates the ground, or is absorbed by the soil.
