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: -For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). River action erodes banks (lithosphere) and uproots plants (biosphere) on the riverbanks.

Detailed explanation-3: -The Water Cycle Connects the Four Earth Systems Water is present in each of the four major Earth systems (hydrosphere, atmosphere, geosphere, and biosphere) and readily moves from one to another. For example, water in the hydrosphere can evaporate to become part of the atmosphere.
