But did you know that water is also inside the Earth? At present, ice locks up a little more than 2 percent of Earth's water and may have accounted for as much as 3 percent or more during the height of the glaciations of the Pleistocene Epoch (2.6 million to 11,700 years ago). In fact, some of the water you see flowing in rivers comes from seepage of groundwater into river beds. Not that long ago, it was believed that our planet formed dry some 4.6 billion years ago, with high-energy impacts creating a molten surface on the infant Earth.

Since the mantle makes up more than half the Earth's mass, it seems likely that mantle water outweighs ocean water, though I can't see how it could get anywhere close to 3% of the Earth's mass. Not only do the oceans provide evaporated water to the water cycle, they also allow water to move all around the globe as ocean currents. Examines the hydrosphere -- which contains all of the Earth's surface water in all of its forms -- and its impact on the environment. The origin of water on the Earth's surface, as well as the fact that it has more water than any other rocky planet in the Solar System, are two of long-standing mysteries concerning our planet.
