GEOLOGY

Detailed explanation-1: -Detailed Solution. The names of the four spheres are derived from the Greek words for stone (litho), air or vapor (atmo), water (hydro), and life (bio). Ozonosphere is a part of atmosphere. That’s why it is not a sphere of the earth.

Detailed explanation-2: -Thus Photosphere is not a layer of atmosphere.

Detailed explanation-3: -Within the boundary of the Earth is a collection of four interdependent parts called “spheres“: the lithosphere, hydrosphere, biosphere, and atmosphere. The spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

Detailed explanation-4: -There are five main systems, or spheres, on Earth.

Detailed explanation-5: -These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air). Each of these four spheres can be further divided into sub-spheres.
