GEOLOGY

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: -Earth’s water makes up the hydrosphere. Hydro means “water. “ The hydrosphere includes the oceans, rivers, lakes, groundwater, and water frozen in glaciers. 97% of water on Earth is found in the oceans.

Detailed explanation-3: -The hydrosphere is often called the “water sphere” as it includes all the earth’s water that is found in oceans, seas, streams, lakes, soil, groundwater, and in the air. The hydrosphere interacts with, and is influenced by, all the other four earth spheres including the cryosphere.

Detailed explanation-4: -The hydrosphere is the aquatic part of the biosphere. This includes oceans, rivers, lakes and other bodies of water. Unlike the lithosphere and the atmosphere, every portion of the hydrosphere supports life.

Detailed explanation-5: -Everything in Earth’s system is placed into one of the four subsystems: land, water, living things, or air. The subsystems are known as “spheres.” Specifically, they are known as the geosphere (land), hydrosphere (water), biosphere (living things) and atmosphere (air).
