Here are some facts about the Hydrosphere

 

​

The Hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. The hydro sphere is all the water on the Earth's surface, such as lakes and seas, and sometimes including water over the Earth's surface, such as clouds.
