EVERYDAY SCIENCE

Detailed explanation-1: -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).

Detailed explanation-2: -The spheres are the biosphere, the geosphere, the hydrosphere, and the atmosphere. Together they are responsible for creating and maintaining the climate, geological processes, and life on Earth.

Detailed explanation-3: -The four spheres of Earth are closely connected to each other. Birds(biosphere) fly through the air (atmosphere), and water (hydrosphere) flows through the soil (lithosphere or geosphere). The spheres of the earth are closely connected to each other. A change in one sphere results in a change in two or more spheres.
