Water is the most abundant and inexhaustible natural resource. It is constituted of the elements Hydrogen and Oxygen. |
| Water ordinarily exists in the liquid state. However on solidifying, it forms ice whereas water vapour or steam are the gaseous forms of water. |
| Water is essential for sustenance of plant and animal life.Various sources of water on earth are ponds, lakes, rivers and oceans. |
| In the water cycle, also called HYDROLOGICAL CYCLE, water from these sources evaporates to form water vapour. |
| These vapours form clouds. On cooling, the clouds condense to form water droplets which are brought back to earth as rain water |
