Study Notes
Water Cycle
- The water cycle is an endless process of water movement around the earth.
- Evaporation occurs when the sun heats water bodies (rivers, lakes, oceans) turning it into vapor.
- The vapor rises into the air.
- Condensation happens as the water vapor cools in the air. This changes the vapor back to liquid water, forming clouds.
- Precipitation occurs when the clouds become saturated with water and release it as rain, hail, sleet, or snow.
- Collection is when precipitation gathers on Earth, in oceans, rivers, lakes, ponds, or underground as groundwater.
- The collected water eventually evaporates, restarting the water cycle.
Importance of Water
- All life on Earth depends on water.
- The presence of liquid water is a key indicator of potential life on other planets.
- Water exists in all three states of matter (liquid, gas, and solid) throughout the water cycle.
