The Water Cycle
Water is a renewable resource. Its' Cycle (also known as the hydrologic cycle) is simply the journey water takes as it circulates from the land to the atmosphere and back again.
With the help of the diagram below, let us see how the cycle works:
Let us start this cycle with precipitation. This is water that start as tiny water droplets, and become larger drops that fall from the sky (atmosphere) in the form of snow, rain and due.
Precipitation creates run-off, which adds to flowing water and end up in rivers, streams, lakes, lagoons and seas.
Some of the water also percolates (seeps through the soil) and into underground water.
The collected surface water then evaporates (turns into gas) and ends up as water vapour in the atmosphere. Condensation occurs and the water vapour it turned into rain-bearing clouds. In addition to that, plants absorb moisture, which also evaporates from the leaves into the atmosphere. This means there is more evaporation in regions with more water bodies and massive vegetation and tend to have more rain bearing clouds.
Rain bearing clouds then release the water in the form of precipitation and the cycle begins again.
