What percent of Earth's surface is water?

Explanation:
Water covers most of Earth's surface when we measure by area, not volume. The oceans and other bodies span about seven-tenths of the planet’s surface, with land making up the rest. The commonly cited figure is 70.8%, which is why that option is the correct choice—it’s the precise surface-area percentage of water on Earth, often rounded to about 71%. The remaining 29.2% is land.
