What is the estimated volume of water that covers the earth?
33 million cubic miles
330 million cubic miles
33 thousand cubic miles
330 thousand cubic miles

The correct answer is - 330 million cubic miles.

The Earth is dominated by water, which surpasses the land area by far. This water also has a great volume, with the estimates being around 330 million cubic miles.

Most of the water is a salt water, with approximately 97.5% of the total volume of the water on the planet, and only 2.5% being fresh water. What's even more interesting is that out of those 2.5% of fresh water, only 0.3% are actually in liquid form, while all the rest is frozen, mostly on and around the poles of the planet.
