What proportion of the earth’s surface is occupied by the waters of the World Ocean?

The oceans are the main and very important part of the hydrosphere, the continuity of the Earth’s water surface, which surrounds both continents and islands, and at the same time has the same salt composition, but an insignificant difference in density. Continents, in turn, divide it into oceans. 96% of the water on the entire Earth belongs to the World Ocean, which is 1338 cubic meters. km. 70.8% – so much it occupies the entire surface of our planet.
