The earths system is divided by four large subsystems, these subsystems are atmosphere, biosphere, lithosphere, and hydrosphere. Atmosphere is the “envelope” of gases that surrounds the earth protecting the earth in a way. Biosphere is the system of living and recently dead organisms on Earth. Lithosphere is the Earth’s rocky outermost layer, and finally hydrosphere is the system of all the Earth’s bodies of water and ice, on the surface and underground. As explained in chapter one in figure 1.8 interconnected cycles; “The hydrologic cycle circulates water through various reservoirs: the ocean, the atmosphere, the lithosphere, and the biosphere. The cycle is completed when the water returns to the ocean. The rock cycle describes crustal processes through which rocks are

The tectonic cycle explains where igneous rock comes from and how new crust is formed and recycled by large scale motions of Earths surface and interior. The sun provides the energy that powers the hydrologic cycle. Heat from the Earths interior powers the tectonic cycle, and the rock cycle draws energy from both sources. Each system is depended on by people, hydrosphere is water, atmosphere is protection, biosphere helps the growth of life, and the lithosphere is the foundation of the Earth....
