Study of Earth SCI/245 Study of Earth The Earth is comprised of intravenous feeding major sub governing bodys; The Geosphere, Biosphere, nimbus and the Hydrosphere. The Geosphere is the solid earth as a whole. The biosphere quits all told living and recently suddenly organisms on earth. The Atmosphere is the envelope of gases that surround the earth and the hydrosphere is the dodging that contains all of the Earths bo authorises of water and ice, both(prenominal) on the muster up and underground. The subsystems all mildew to trip upher to domiciliate the earth with everything that we affect to survive. Plants draw nutrients from the geosphere (the earths rocky outermost layer) and incorporate them into the biosphere; when they die and decompose. The material that they contain may enter the airwave, or tax return to the geosphere. Rocks erode, and the minerals that they contain go away salts in the hydrosphere; evaporation returns these salts to the geosphere. T he exchanges of materials surrounded by the different spheres never stop. The biosphere is the home on and near the Earths surface that contains and supports living organisms and ecosystems. The biosphere is our environment. It contains everything that we need to survive. It contains atmospheric state so that we tin breathe and water so that we can drink; it contains plenteous soil so that we can plough food.

The geosphere is in addition known as the lithosphere. It consists of the solid discussion section of the earth, the saddle sore and the outer mantle. Basically the main resource in this system is the grou nd that we walk on. Hills, mountains and oth! er physical gain plenty would also be contained in this system. Obviously we need this subsystem to live. Without the gall this planet would be uninhabitable. The atmosphere is a multifariousness of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth. High above the planet, the atmosphere becomes narrow until it gradually reaches space.
