The Water Cycle

Here we have a complete Geography Crossover topic.
The watercycle is a fundamental and important part of chemistry....
I sure most of u guys did this already,and we touched on this in form 2 Integrated Science but just for review, here it is--

The Water Cycle


There will never be any more freshwater on Earth than there is now. No new water is being made and water can’t escape from the Earth. The water we use is recycled over and over again.

The water cycle is the simplest natural cycle on Earth. Solar energy evaporates water from the ocean, lakes and rivers. Millions of litres of water rise into the atmosphere as an invisible gas - water vapour. This process is called evaporation.

As the water vapour is pushed over the land by winds and rises over mountains, the water vapour cools and turns back into tiny water droplets, forming clouds. The droplets joining together is termed condensation. These droplets fall to earth as rain (precipitation).

The rain runs into streams and rivers, which eventually flow into lakes or the sea and the cycle begins all over again.
