The major importance of the hydrosphere is that water sustains various life forms and plays an important role in ecosystems and regulating the atmosphere. Hydrosphere covers all water present on the Earth’s surface. It involves saltwater, freshwater, and frozen water along with groundwater and water in the lower levels of the atmosphere. The following are the functions of a hydrosphere.
