Study of Earth
The Earth is comprised of four major subsystems; The Geosphere, Biosphere, nimbus and the Hydrosphere. The Geosphere is the solid earth as a whole. The biosphere quits all told living and recently dead organisms on earth. The Atmosphere is the envelope of gases that surround the earth and the hydrosphere is the system that contains all of the Earths bodies of water and ice, both(prenominal) on the surface and underground.
The subsystems all work to trip upher to domiciliate the earth with everything that we affect to survive. Plants draw nutrients from the lithosphere (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 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. The exchanges of materials between 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 displace breathe and water so that we can drink; it contains fertile soil so that we can plough food.




The geosphere is also known as the lithosphere. It consists of the solid discussion section of the earth, the crust and the outer mantle. Basically the main resource in this system is the ground that we walk on. Hills, mountains and other physical gain masses would also be contained in this system. Obviously we need this subsystem to live. Without the crust 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 thinner until it gradually reaches space. It is divided into five layers. Most of the tolerate and clouds are found in the first layer.
