Biogeology is the study of how the The biosphere is that part of a planet earths outer shell—including air, land, and water—within which life occurs, and which biotic processes in turn alter or transform. From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings... biosphere and the The lithosphere (from the Greek for rocky sphere) is the solid outermost shell of a rocky planet. On the Earth, the lithosphere includes the crust and the uppermost layer of the mantle. It floats on the more plastic asthenosphere. The thickness of the lithosphere varies from around 1.6 km... lithosphere interact.

The term mineral encompasses not only the materials chemical composition but also the mineral structures. Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms (organic compounds are usually excluded). The study... minerals such as The mineral pyrite, or iron pyrite, is iron disulfide, FeS2. It has isometric crystals that usually appear as cubes or pyritohedrons. It has a slightly uneven and conchoidal fracture, a hardness of 6 - 6.5, and a specific gravity of 4.95 - 5.10. Its metallic luster and pale-to... pyrite and can concentrate economically important For alternative meanings see metal (disambiguation). In chemistry, a metal (Greek: Metallon) is an element that readily forms cations and has metallic bonds, and it is sometimes said that it is similar to a cation in a cloud of electrons.

Rocks are classified by mineral and chemical composition; and also by the processes that formed them. Rocks are thus separated into igneous, sedimentary, and metamorphic rocks. Igneous rocks are formed from molten magma, sedimentary rocks by deposition and compression... rocks.
