The Hydrophere- What is it?

The hydrosphere is all the water found on, under, or over the surface of a planet.

The "Water Planet"

         If you look down at our planet from outer space,

most of what you see is water;

71% of the planet's surface is covered by ocean and it is

because of this that the Earth is sometimes called "the water planet". 

Only about three-tenths of our globe is covered with land.
