Hydrosphere: Two – thirds of the Earth’s surface is surrounded by water which is present in seas and oceans. The presence of water is found in small or large reservoirs. In addition to the depth, there are wide variations in water.
The origin and distribution of seas and oceans on the earth, the physical and chemical properties and structure of the sea, water, ocean currents, ocean deposits, temperature in oceans, salinity, density, tide, coral reefs, waves, ocean profiles, etc. are included in this. Different types of motion are found in the water bodies. Limitless stores of organic and inorganic resources are also found in the hydrosphere. All the above facts are studied in context to the water bodies under hydrosphere.
