Detailed explanation-1: -A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet’s hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers.

Detailed explanation-2: -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. Of all of that water, only about three percent is freshwater.

Detailed explanation-3: -The word hydrosphere comes from the Greek words for “water” and “ball.” It is the term used to talk about all of the water on our planet Earth.

Detailed explanation-4: -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.

Detailed explanation-5: -Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air).
