Minerals and Rocks


MINERALS:

Minerals are the building blocks of rocks.  The main minerals of Earth include quartz, feldspar, hornblende, and mica.

This mineral is Quartz. I chose it because it is the most common mineral.

Rocks: 

Rocks are the more complex structures, being made of minerals.  The main rocks we see are granite, diorite, sandstone, kaleonite, coquinas, and limestone.  However, there are three types of rocks: igneous rocks (rocks cooled from lava or magma), metamorphic rocks (igneous rocks that go through changes to make a re-crystalized rock), and sedimentary rocks (sediment that molds together to turn into rock).

This igneous rock is granite, which is a mix of the minerals quartz, feldspar, and hornblende.  The metamorphic rock I chose is gneiss, which is a metamorphosis of granite.  This sedimentary rock is the coquina rock, which is made of sand and shells.
