Transcript SPHERES
Earth’s System • Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. • These four subsystems are called "spheres." Atmosphere What is it? DEFINITION: The gaseous layer that surrounds the Earth. Hydrosphere http://www.cmmacs.ernet.in/~himesh/Hydrosphere%20Components.gif What is it? DEFINITION: All the water on the Earth. ( solid, liquid and gas) Hydrosphere Distribution Lithosphere What is it? DEFINITION: The Earth’s solid surface which includes the continental and oceanic crust and the upper mantle. Biosphere What is it? DEFINITION: All life on Earth and where it exists. • In addition to the four spheres mentioned, there is one more added and it is due to the presence of our worldly presence. Anthrosphere What is it? DEFINITION: Everything we build/human construction. Some Spheres for Fun • • • • • • Magnetosphere or geomagnetosphere is in space, protects us from solar winds and suns radiation Asthenosphere is the nonrigid layer below the lithosphere, convection currents within move the tectonic plates Geosphere is the densest parts of Earth, which consist mostly of rock and a heterogenous mixture. The dense geosphere is also subdivided into the crust, mantle, and core. Pedosphere is the outermost layer of the Earth that is composed of soil and subject to soil formation processes. It exists at the interface of the lithosphere, atmosphere, hydrosphere and biosphere. Ionosphere or plasmasphere is a sub sphere of the atmosphere, outermost part Cryosphere is the portions of the Earth’s surface where water is in solid form; including sea ice, lake ice, river ice, snow cover, glaciers, ice caps and ice sheets, and frozen ground (which includes permafrost).
