Igneous rocks are the "original"rock.
Most igneous rocks are under the surface of the Earth.
What type of rock do you think is most prevalent ON Earth's surface?
- Think/Pair/Share
WHY??
Sedimentary rocks make up 75% of the surface rocks on Earth.
Why?
Sedimentary rocks often formed near ancient water sources (rivers, lakes, ocean...) Why?

Detrital – made of fragments of rock cemented together with calcite or quartz
Different sized grains = different types of detrital rocks...
Gravel - Congomerate
Sand - Sandstone
Silt - Siltstone
Clay - Shale
Chemical rock – minerals crystallize out of solution to become rock
Limestone is a sedimentary rock made of calcium carbonate (CaCO3) - the mineral calcite. It most commonly forms in clear, warm, shallow marine waters.
-It is usually an organic sedimentary rock that forms from shell, coral, algal and fecal debris.
Organic rock – remains of plants and animals
Coal is an organic sedimentary rock that forms from the accumulation and preservation of plant materials, usually in a swamp environment.
Coal is a combustible rock and along with oil and natural gas it is one of the three most important fossil fuels.

Gneiss is foliated metamorphic rock that has a banded appearance and is made up of small mineral grains.
It typically contains abundant quartz or feldspar minerals.
Marble is a non-foliated metamorphic rock that is produced from the metamorphism of limestone.
It is composed primarily of calcite.
Amphibolite
Quartzite
Phyllite
Foliated
