Specifically, they are the "geosphere" (land), "hydrosphere" (water), "biosphere" (living things), and " atmosphere " (air). Thereof, what is the importance of Earth subsystems? The geosphere has four subsystems called the lithosphere, hydrosphere, cryosphere, and atmosphere. Because these subsystems interact with each other and the biosphere, they work together to influence the climate, trigger geological processes, and affect life all over the Earth . Additionally, what is Earth's largest system? These spheres are further divided into various sub-spheres. According to Wikipedia, “ Earth is the third planet from the Sun, the densest planet in the Solar System , the largest of the Solar System's four terrestrial planets, and the only astronomical object known to harbor lif...
