• Identified by look and certain tests
         Examples

• Identified because of its layers.

• Type of rock depends on what is in sediment.

• Fossils found in some
            Examples

Sandstone
            Igneous Rock

                                  Pumice
  Granite
        Metamorphic Rock

• Rock that has changed because of heat
