The swing turn Weathering-erosion-deposition=sedimentary-conpactation and cementation-metamorphism= metamorphic, cooling solidification = pyrogenic The fray cycle shows the major factors affecting swing and rolls below and preceding(prenominal) the surface. It comprises of three stages -creation, adaptation and destruction, Rocks are constantly being eroded and wea in that respectd. Wind, water, ice and animals whole wear waver muckle. The eroded swing fragments move down to the bottom of mountains and rivers causing them to layer. This is where sedimentary contestation is form.

There are two types of igneous rock intrusive (intrusive) and volcanic (extrusive) Plutonic or volcanic are formed below the earth surface.an example would be Granite.

Granite rock is unremarkably a pink to dark greyness in contort. The colour normally depends in the mineral content.Hight levels of felspar will make water it the pink colour. The minerals in granite are feldspar, quaritz and micra. Granite forms slowly allowing crystals to form. It is formed when it was intruded into exiting rock of the earth! s crust. This occurs amid 2-50km underneath continental crust. Granite has a course to medium grain and it is a tough rock. Granite is a lot used in construction for gravestones and monuments. An Irish example of the igneous rock granite is in the Mourne Mountains and the Wicklow mountains. How 2 intrusive features are created.
