Earth Spheres :: essays research papers fc

DEFINITIONSThe biosphere is a closed self-regulating system that integrates nourishment organisms with nonliving components of a satellite (Lenkeit). The biosphere is part of the outer shell of a planet and includes the gentle wind, hydrosphere, and lithosphere (answers.com). The hydrosphere is an plainspoken system that contains all of a planets solid, liquid, and vaporous water (Answers.com). As an open system, the hydrosphere interacts with the surrounding systems through inputs and outputs (Lenkeit). The atmosphere is an open system that consists of a gaseous mixture enveloping a planet (Answers.com). These gasses, known as air, include O2, N2 and H2O. The atmosphere is also composed of water, ice rink and dust particles. Atmosphere functions like a blanket, keeping Earths heat from escaping into quadriceps femoris (Lenkeit). It has also been compared to a greenhouse like glass it lets short cockle insulation inside, but keeps most of long wave ground radioactivity from going out (Lenkeit).The lithosphere is an open system, which contains all of the cold, hard, solid gemstone and roll of the planets crust (surface), the hot semi-solid rock that lies underneath the crust, the hot liquid rock near the center of the planet, and the solid iron core (center) of the planet (Answers.com). On Earth, the lithosphere comprises the crust and the upper part of the mantle. The lithosphere is about threescore miles thick (Lenkeit). INTERACTIONSThe four spheres of the Earth system are highly dependent causing interactions between the spheres to have many cause and effect relationships. A change in one sphere can cause changes in another sphere, which may cause changes in yet another sphere. The biosphere is prolong through interactions with the gasses from the atmosphere, minerals of the lithosphere, and water of the hydrosphere in the energy cycle (Answers.com). The atmosphere is all-important(a) for the biosphere because it supplies oxygen, water, CO2 an d some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation syndrome (Answers.com). Outside of the biosphere, the atmospheric interacting with the lithosphere and hydrosphere is when the ocean waves are affected by the wind being slowed by friction from the land (Lenkeit). The lithosphere interacts with the hydrosphere and atmosphere through processes such as erosion where rock and soil lead removed through physical and chemical weathering.
