Lithosphere

Notes on the lithosphere- (rock sphere) Upper most part is crust of earth. Compiled of rocks of outer crust. Outermost shell. Upper part- rocks we see at and near the earths surface. Crust is 5 to 10 km thick under most oceans and 24 to 60 km thick under the continents. The lithosphere under the crust is solid, dense material. (more dense than surface materials). Lithosphere 100-200 km. Notes on the aesthenosphere- zone beneath the lithosphere. Thick like tar. Weak because of high teperatures at that depth. Density- 2.7-3.4 to about 12. Notes on the hydrosphere- (Water-bearing) Too small due to the irregularity of upward projection. Density-1.1 Notes on the Atmosphere- only 10 km thick layer of gas which is the basis of human life. Dens. 0.0.
Reactions within- litho to hydro, none besides movement of sand and other free floating particles, absorbtion. Hydro to atmo, evaporation, precipitation, mater, energy, gases, salt, oxygen, carbon dioxide. Litho to atmo, none besides precipitation. Silicon tetrahedron- tetrahedron, a shape of a crystal. If a quartz crystal, (SiO) is broken, then it would shatter. A feldspar (Al,Si,O,Ca,Na) is split, it would evenly cleave. Of all rocks- O=46% Si=28%. Basic structure- 4 oxygen, one Si, i n the shape of a pyramid. Such a foundation is a Si tetrahedron. Silicates are the most common family of minerals. Tetrahedrons- Si + O2= 75% of all. Rocks are classified- by how they are formed. Igneou
