What percentage of Earth’s surface is covered by water?
A 59%
B 71%
C 84%
Fact: Remember that one from elementary school? Oceans and seas hold about 97% of all the water on Earth. About 2.5% is fresh water, though most of that is frozen or stored in the ground and is inaccessible for drinking. As far as what percentage of the oceans is currently protected, that number is hard to pin down because it depends on how you define ‘protected.’ Estimates often hover between 2% and 8%.
Correct Answer: 71%
