The water cycle, also known as the hydrological cycle, is the continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, and transpiration, through which water circulates between the atmosphere, land, and oceans.


The importance of the water cycle lies in its role in maintaining the Earth's ecosystems and supporting life. Some key points about its importance include:

  • It helps distribute fresh water across the planet, replenishing rivers, lakes, and groundwater sources.
  • It regulates the Earth's temperature through processes like evaporation and transpiration.
  • It plays a crucial role in agriculture by providing water for crops and plants to grow.
  • It influences weather patterns and climate, impacting regions around the world.
  • It helps in the natural purification of water through processes like evaporation and condensation.

Overall, the water cycle is essential for sustaining life on Earth and supporting various ecosystems.
