Detailed explanation-1: -One of the main components of Earth’s interdependent physical systems is the hydrosphere. The hydrosphere is the sum of Earth’s water, in the ocean, the ground, on the surface, and in the air. Approximately 71 percent of Earth’s surface is covered in water.

Detailed explanation-2: -Surface water is any body of water found on the Earth’s surface, including both the saltwater in the ocean and the freshwater in rivers, streams, and lakes.

Detailed explanation-3: -The hydrosphere is the component of the Earth that is composed of all liquid water found on the planet. The hydrosphere includes water storage areas such as oceans, seas, lakes, ponds, rivers, and streams. Overall, the hydrosphere is very large, with the oceans alone covering about 71% of the surface area of Earth.

Detailed explanation-4: -The total water present on earth is called as hydrosphere. It includes water sources, like ocean water, glaciers, rivers, lakes, ponds, atmospheric water (moisture) and groundwater.

Detailed explanation-5: -Hidden in the Earth’s crust are vast stores of “groundwater, ” water that fell from the sky and then trickled into the cracks and crevices between the sand, gravel and rocks beneath our feet. This resource makes up 95% of the freshwater that is not tied up in glaciers or ice caps.
