This rock I identified as igneous is mostly gray with red, green, and shiny silver spots. There are two different types of igneous rocks, intrusive and extrusive. Intrusive igneous rocks cool slowly because they crystallize below the Earths surface. This causes large crystals to form, like in the picture below. .
Metamorphic Rock:
This rock had several thin layers parallel to itself which is why I identified it as a metamorphic rock. There are two types of metamorphic rocks, foliated and non-foliated. Foliated rocks have a layered appearance that is formed by exposure to heat and pressure.
Sedimentary Rock:
I noticed the fossil in this rock and concluded that it is a sedimentary rock. Sedimentary rocks form at a temperature and pressure that do not destroy fossil remnants.
