The share of land (continents and islands) accounts for about 149 million km (squared) of the entire surface of the earth.

The share of land (continents and islands) accounts for about 149 million km (squared) of the entire surface of the earth. And how much of the earth’s surface is the share of the World Ocean?

If we take into account the fact that the total area of the earth’s surface is 510 million square kilometers, then in order to determine the total area of the World Ocean, it is necessary to subtract the land surface area from the Earth’s surface area.

In this case, get:

510 – 149 = 361 million square kilometers.

If we convert these values into percentages, we get:

149/510 * 100% = 29.2% (Occupies the land surface).

361/510 * 100% = 70.8% (Occupies the surface of the World Ocean.)
