The Water of the Earth.

1. How much moisture is involved in the giant process of ocean-atmosphere-land-ocean?

What is the mechanism of this conveyor thanks which moisture gets from the ocean to the land and back?

It has been estimated that a total flow of 577000 cu km of water annually evaporates on our planet, chiefly from the surface of the ocean. 2.The bulk of water reserves on the planet were considered to be unlimited. Water seemed to be an inexhaustible gift of nature and has become a factor limiting the development of vast areas of the globe. Mankind now uses about 2600 cu km - roughly 6 per cent of the annually renewable reserves of fresh water. 3.1t would seem that the reserves of water supply are great. Unfortunately, this is not so. The threat of a water crisis is becoming obvious. One of the main reasons is the growing pollution of surface waters.

4.The most realistic way to the solution of the water problem is through rationalizing the use of nature. The water of the planet can and must remain pure.
