What is hydrosphere ?

The hydrosphere is often called the “water sphere” as it includes all the earth’s water that is found in oceans, seas, streams, lakes, soil, groundwater, and in the air.

The hydrosphere interacts with, and is influenced by, all the other four earth spheres including the cryosphere. Water is found in vapor, liquid and solid states phases in the atmosphere. The hydrologic cycle traces the movement of water and energy between these various stores and spheres.
