Study Notes
The Water Cycle
- The water cycle is the continuous movement of water on Earth, without a beginning or end.
- It involves a cyclical process of evaporation, condensation, precipitation, and collection.
- Evaporation: The sun heats water in rivers, lakes, and oceans, turning it into water vapor.
- Condensation: Water vapor in the air cools and changes back into liquid, forming clouds.
- Precipitation: Clouds become heavy when water condenses, releasing water back to Earth as rain, hail, sleet, or snow.
- Collection: Precipitation collects on Earth in oceans, rivers, lakes, ponds, and groundwater.
- The water cycle begins again with the evaporation of collected water.
The Importance of Water
- Water is essential for all life on Earth.
- The presence of liquid water is a key indicator of potential life on other planets.
- Water can exist as a liquid, gas, or solid due to its role in the water cycle.
