Question

Seas and oceans play an important role in supplying water for our use. How?

Answer 1

The water we consume ultimately comes from the sea: because of sunlight, water heats up and evaporates into theatmosphere, where lower temperatures transform steam into droplets, which create clouds. ... More than 97% of the water on earth is in the oceans –the rest is found in glaciers, on lands and in the ground.
