Answers
Answer: MAY THIS HELPS YOU...!!
Explanation:
We rarely think about the role of the planet that keeps us alive and take hydrosphere for granted. The major importance of 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 surface. It involves saltwater, freshwater and frozen water along with groundwater and water in the lower levels of the atmosphere. Following are the functions of a hydrosphere.
Water is the most important part of living cells
Every cell in living organism is built up of about 75% of water, hence allows the cell to function appropriately. Cells would not able to carry out normal functions and life cannot exist without water.

Water provides habitat
Hydrosphere provides place for many plants and animals to live. Many gasses like CO2, O2, nutrients like ammonium and nitrite(NO–2) as well as other ions are dissolved in water. The presence of these substances is essential for life to exist in water.
Regulate Climate
The water’s specific heat is its unique characteristics. This indicates that water takes a lot of time to heat up and a lot of time cool down. It helps in regulating temperatures on earth as they stay in a range which is acceptable for life on earth to exist.
These are only a few of the functions that water plays on the planet. Many functions relate it to chemistry and methods in which it dissolves substances.
