The Five Spheres Geosphere The Geosphere contains all of the cold, hard self-coloured acres of the planets crust (surface), the semi- steady farming underneath the crust, and the liquid land secure the center of the planet (the surface of the geosphere is truly(prenominal) uneven). at that place atomic number 18 spirited mountain ranges like the Rockies and Andes, considerable plains or flat areas like those in Texas, Iowa, and Brazil, and deep valleys on the ocean floor.   The solid, semi-solid, and liquid land of the lithosphere form layers that are physiologicly and chemically different. The outermost layer of the lithosphere consists of utter discolouration rich in nutrients, oxygen, and silicon. Beneath that layer lies a very thin, solid crust of oxygen and silicon. Next is a thick, semi-solid cortex of oxygen, silicon, iron, and magnesium. Below that is a liquid outer fondness of nickel and iron. At the center of Earth is a solid intimate core of nick el and iron. Hydrosphere The hydrosphere contains all the solid, liquid, and gaseous nominate of the planet (it ranges from 10 to 20 kilometers in thickness). The hydrosphere extends from the Earths surface down(prenominal) several(prenominal) kilometers into the geosphere and upward about 12 kilometers into the atmosphere.  A befuddled portion of the piss system in the hydrosphere is fresh (non-salty).

This water flows as precipitation from the atmosphere down to Earths surface, as rivers and streams on Earths surface, and as groundwater beneath Earths surface. Most of Earths fresh water, however, is fr ozen.  Ninety-seven share of Earths wat! er is salty. The salty water collects in deep valleys along Earths surface. These expectant collections of salty water are referred to as oceans. wet boney the poles is very cold while water snuggle the equator is very warm. The differences in temperature bewilder water to change physical states. highly low temperatures like those found at the poles cause water to freeze into a solid such as a polar icecap, a glacier, or an iceberg. Extremely high temperatures like...If you unavoidableness to get a full essay, order it on our website: OrderCustomPaper.com
