Granite is an intrusive igneous rock which is well known because of its salt and pepper colour

Diorite is a form of granite and looks very similar to it

Pumice is an extrusive igneous rock that is most known for its porous texture

Basalt is an extensive igneous rock with a curved and glassy texture

Sandstone is a clastic sedimentary rock formed by compressed sand particles

Conglomerate is a clastic sedimentary rock which is formed by small pieces of gravel stuck together with red mud

Shale is a clastic sedimentary rock which is formed by compressed silt or mud

Rock salt is a chemical sedimentary rock where it is formed by sediments that are discovered after water evaporates

Chert is a chemical sedimentary rock comprised mainly of quartz

Dolomite is a chemical sedimentary rock comprised of calcite

Coal is an example of organic sedimentary rock and is mostly comprised of dead plant material compressed over the years

Coquina is an organic sedimentary rock comprised of the shells of dead molluscs or clams

Chalk is a variety of limestone which is known for its fine texture

Gneiss is a foliated rock where schist and other igneous rocks are put through intense heat and pressure

Slate is a fine grained and foliated rock, which is created under the alteration of shale or mudstone

Schist is a foliated metamorphic rock

Marble is a hard smooth rock made by limestone or chalk through strong heat and low pressure

Quartzite is created through high heat and pressure on quartz rich sandstone, which effectively fuses them together

Hornfels is a non foliated metamorphic rock which is usually quite dark in colour
