I'm trying to learn about the different kinds of rocks.

Rocks are made up of minerals, which are composed of atoms arranged in a crystal lattice. There are many different types of minerals, but they all have similar properties and chemical compositions. The most common minerals found in rocks include quartz, feldspar, calcite, and mica. Other less common minerals can also be present, such as pyrite (iron disulfide), barite (barium sulfate), and zircon (zirconium silicate).
