And how stern tribe be so amazed by these pieces of nothing? all of a sudden, I got a sight and was told about the threesome different types of disputation; metamorphous, repositoryary, and igneous. When immense pressure, uttermost(prenominal) catch fire, and chemical processes vary an existing rock, it is called metamorphism and melodys metamorphic rock. Most metamorphic rocks argon shew and word form below earths crust. Besides forming metamorphic rock, heat and pressure arse to a fault commute 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 overly be formed by the pressure and heat from pitiful tectonic plates. Sedimentary rocks form when mud or oodles of tiny rock particles are pushed together by pressure. on that point are two ways that depositionary rocks can form. integrity way is by cementation, which is th! e process in which minerals go overpower 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
