The water cycle.


The water cycle may be a continuous cycle by which water circulates between the Earth's oceans, atmosphere and land. It involves various processes like evaporation, condensation, precipitation and transpiration. During the water cycle, water goes through different states-solid, liquid and gas.

  Due to the  heat  of the Sun, water evaporates continuously from various water bodies like oceans, seas, rivers, lakes, ponds and streams and forms water vapour . Plants also release huge amounts of water vapour within the air through transpiration, The water vapour , being lighter, rises up within the atmosphere. above within the atmosphere, the air starts becoming cooler. As a result the water vapour cools down and condenses on dust particles present within the atmosphere to make tiny water droplets. These droplets are so small that one large suitcase would contain 100 million droplets!


Many tiny water droplets combine together to make a cloud.If the air is extremely cold, the cloud is formed from tiny ice crystals. Gradually, the small water droplets stay together and form bigger drops. When the clouds become too heavy and can't hold the water drops, these drops fall to the surface as rain. this is often called precipitation.



Precipitation refers to any sort of water like rain, snow, sleet or hail, which falls to the surface from the atmosphere. it's through precipitation that water involves the world . Sometimes while passing through the atmosphere, liquid rain comes in touch with very cold air, and freezes on the way. It then falls as snow, sleet or hail.


 The rainwater runs off over land and fills the ponds, lakes, rivers and oceans. This manner the evaporated water comes back to the world . Some rainwater falls to the land and flows beneath the surface through tiny pores within the soil. This is often called percolation. This water goes at heart into the soil and collects as groundwater. Groundwater is drawn out using wells and electrical pumps.
