what is Hydrosphere?
The hydrosphere is the combined mass of water found on, under, and above the surface of the earth. It has been estimated that there are 1386 million cubic kilometres of water on earth. This includes water in liquid and frozen forms in groundwater, oceans, lakes and streams. Approximately 75% of Earth’s surface, an area of some 361 million square kilometres, is covered by ocean.
