How much of the Earth is covered by sea?
|
Some scientists say we should call our planet 'Water' instead of 'Earth', since water covers about 71 percent of the planet's surface. The area of the ocean surface is 1.40 x (10 to the power of 8) milesē. (3.62 x (10 to the power of 8) kmē). The area of the land surface is 5.75 x (10 to the power of 7) milesē (1.49 x (10 to the power of 8) kmē). There is over 2.4 times as much water area than land area. | | A world map shows at a glance just how much of the Earth's surface is covered by water. |
