The Rock Cycle & Classification of Rocks The rock cycle is the formation‚ breakdown and reformation of a rock as a result of sedimentary‚ igneous‚ and metamorphic processes.

Formation of Rocks The three main ways rocks are formed: • Sedimentary rocks are formed through the gradual accumulation of sediment: for example‚ sand on a beach or mud on a river bed. As the sediment is buried it is compacted as more and more material is deposited on top. Eventually the sediment will become so dense that it is essentially rock. This process is known as lithification. • Igneous rocks are rocks which have crystallized from a melt or magma. The melt is made up of various components

The rock cycle involves of a chain of continual progressions through which earth materials change from one form to another over time. Some processes in the rock cycle happen over millions of years and others occur much more quickly. There is no real starting or completion to the rock cycle; however‚ it may be appropriate to begin investigating the rock cycle with magma (Bergman 2005).
