Most metamorphic rocks argon base and organize below earths crust. Besides deviseing metamorphic rock, heat and pressure arse to a fault smorgasbord one mineral into another. Scientists can tell how the rock was formed and how much heat and pressure there was at the time of the metamorphism by the composition of the rock.

Metamorphic rock can as well be formed by the pressure and heat from sorrowful tectonic plates. Sedimentary rocks form when mud or tons of tiny rock particles are pushed t ogether by pressure. there are two ways t! hat sedimentationary rocks can form. matchless way is by cementation, which is the process in which minerals go megabucks into pore spaces between sediment grains and bind sediments together and form rock. The other way sedimentary rocks are formed is by a process called compaction. Compaction is when the volume and porosity of sediment is decreased by the weight of overlying sediments as a result of burial beneath other sediments. There are three classifications for sedimentary rocks, shape size, and composition. When magma cools...If you want to get a full essay, order it on our website: BestEssayCheap.com
