Homework

Diagram of the rock cycle on a poster board with the 3 types of rocks and all the processes that drive the cycle. Due Thursday 11/6/14 worth 200 pts

rGLE 0707.7.2 Summarize the basic events that occur during the rock cycle. ocks

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?

From One Rock to another

On a RECYCLINGRoute

But never in a hurry

RRoocckk CCyycclle ?e ?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 earthcan be thought of as a giant recycling machine;rocks are neither created nor destroyed, but redistributed and transformed from one rock type to another.

The RRoocck k CCyyccllee involves the recognition of three main classes of rocks.

The three rock types are …
