What is the Water Cycle?
The water cycle, also known as the hydrologic cycle, is a continuous process that describes how water moves through the environment. It consists of several key stages:
- Evaporation: The process begins when the sun heats up water in rivers, lakes, and oceans. This heat causes the water to transform into vapor and rise into the atmosphere.
- Condensation: As water vapor rises, it cools and condenses into tiny droplets, forming clouds. This occurs when the temperature drops at higher altitudes.
- Precipitation: When the water droplets in clouds combine and grow larger, they eventually fall back to earth in the form of rain, snow, sleet, or hail.
- Collection: Precipitated water collects in bodies of water like rivers, lakes, and oceans. Some of it infiltrates the ground, replenishing underground aquifers.
This cycle is vital for maintaining ecosystems, replenishing water sources, and supporting all forms of life. It emphasizes the importance of water conservation, as fresh water is limited. Understanding the water cycle helps us appreciate the planet's processes and the need for sustainable practices.
