ADVERTISEMENTS:
After reading this term paper you will learn about the composition of water cycle present in the atmosphere.
The water cycle is a process where water evaporates from the sea, condenses as clouds, falls as rain and flows into the seas and oceans through rivers and streams and again evaporates due to heat in the air.
i. When rain falls on the ground, some water percolates into the soil and adds to the underground water table. This water from the soil is later used by plants and animals which is released back into the atmosphere either in the form of vapor or liquid.
ADVERTISEMENTS:
ii. When water flows through the rocks, it dissolves the deposited soluble minerals. Thus, rivers carry more minerals from the land to the sea which are used by the marine organisms.
iii. When the snow on the ice caps of the mountains melts, the water flows down into the streams and rivers, and thus enter the water cycle.
