How did the four spheres come into existence on the Earth? |
|
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) HOPE THIS HELPS YOU AND PLEASE MARK ME AS A BRAINLEIST |
