Definition of A Rock : 

Definition of A Rock A rock is a naturally formed solid that is usually made up of one or more minerals. FUN FACTS: Igneous rocks are the oldest kind of rocks. The meaning of the word “metamorphic” means to change. Sea shells, bones and teeth of animals contain calcium witch gets deposited on the sea floor. Over a period of time these debris pile into a layer witch is thick enough to form these types of sedimentary rocks. Julianna

Rock Types :

A rock will get buried deeper in the crust where the rocks get more heat and pressure .And the rock changes . Forms when molten rock cools .It can be formed within Earth on the surface Sedimentary Rocks Forms when pieces of older rocks , plants and other loose material get pressed together .
