spheres on the Earth​

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

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).
