Rocks A rock is a naturally occurring solid mixture of one or more minerals and organic matter. It might be hard to believe but rocks are always changing…..

Which rock will it stay? Can you Figure it Out?

Igneous metamorphic Sedimentary The Rock Cycle

What is the Rock Cycle ? The rock cycle is a sequence of events involving the formation, alteration, destruction, and reformation of rocks as a result of natural processes such as magmatism (melting of rock into magma), erosion, transportation, deposition, lithification, and metamorphism. Glossary of Geology, Bates & Jackson, AGI

The mantle, crust and surface of the earth can be thought of as a giant recycling machine; rocks are neither created nor destroyed, but redistributed and transformed from one rock type to another. March 2000

Rock Cycle The Rock Cycle involves the recognition of three main classes of rocks. The three rock types are …

Minerals combine to form Rocks

Rocks Some Rocks are made up of just one mineral - like rock salt (made up of the mineral halite) Rocks Others Rocks are made up of many minerals - like the granites and gneisses (made up of feldspars, quartz, and other minerals)
