How much of the earth is covered in land?
Less than 30% of the 510 million square kilometers of area on the Earth’s surface is covered by land. There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans.
How much of the Earth is covered with water?
This is just 1/4400 the total mass of the Earth, which means that while the oceans cover 71% of the Earth’s surface, they only account for 0.02% of our planet’s total mass. Many theories about the origins of water on Earth attribute it to collisions with comets and asteroids.
