WATER IS MOST PRECIOUS SUBSTANCE ON EARTH :-
Water is a precious resource. We can’t live without it. If you look at a map of the world you will see that much of our planet is covered in water. Our oceans are not the only source of water. Water is also present under the ground and as vapor in the air. Clouds formed by this vapor ensure that water falls back down to Earth as rain, sleet, snow or hail.

Ocean water has too much salt in it for us to drink. Much of the water that falls back to Earth in one form or another becomes runoff. It travels some distance over land before making its way back to one of Earth’s oceans. As it travels over land, the water picks up salts and minerals from the rocks and soil and washes them into the ocean. The deposits have built up over many years. That is why ocean water is so salty.
