Rocks

completely throw offs argon eventual(prenominal)ly derived from igneous rock. Do you agree with this contestation? dispute with specific reference to the rock cycle. The Earths crust is be of diverse kinds of rocks, which atomic number 18 composed of minerals. Rocks argon divide into troika major groups, depending on their origin - igneous, sedimentary and metamorphic. All rocks ar stages in a never-ending cycle, the rock cycle, which interminably refashions, redistributes and recycles vivacious crustal secular. The Earths surface is athletic field to constant smorgasbord. Some of this is operate by sub-surface processes much(prenominal)(prenominal) as, plate tectonics, folding, faulting and volcanic activities, which tend to raise the surface. However, somewhat of the change is driven by surface processes such as weathering and eroding which tend to disappoint the surface. The rock cycle whole shebang non-stop building up and article of clothing down the Earths surface materials. The supreme source of all rocks on the Earths surface is magma. Igneous rocks argon formed when molten magma cools and solidifies, all underground or on the surface which results in having meddlesome and extrusive igneous rocks. These rocks are constantly being do for(p) and created. Once they are the whole way at the surface they are weathered, mainly by the do of rain, frost and wind. There are various weathering processes which include atomic number 11 chloride weathering, frost weathering, insolation weathering, root-wedging and total weathering amongst others.

This is a very immaculate example of denudation where weathering prepares material for transport, and mass wasting and eroding move that material downward-sloping towards an ultimate base level, usually the sea. The movement of rock particles is done by active transporting agents such as running water, touching ice or blowing wind. If attestation continues, more material is hide till finally, the sediments are ladened and cemented together to form sedimentary rocks. Other igneous rocks are change into metamorphic...
