# Rocks, Minerals, and Society

Part of the Geology Merit Badge Digital Resource Guide: [Introduction & Overview](https://merit-badge.university/merit-badges/geology/guide/index.md)

*4. Mineral Resources*

> **4.** Option C—Mineral Resources. Do ALL of the following: **Mineral Resources**

This option moves from basic definitions to real-world use. You will study the three rock classes, learn how minerals are identified, choose a collection or identification path, connect geology to roads and construction, and finish with a visit or investigation that shows how society depends on Earth materials.

## What You'll Complete

- **[Req 4c1 — The Three Rock Classes](https://merit-badge.university/merit-badges/geology/guide/req4c1/)**: Define rock and compare igneous, sedimentary, and metamorphic origins. You will gain the core classification system of geology.
- **[Req 4c2 — What Makes a Mineral](https://merit-badge.university/merit-badges/geology/guide/req4c2/)**: Define mineral and learn the physical properties geologists use for identification. You will gain hands-on vocabulary for mineral testing.
- **[Req 4c3 — Collect or Identify Specimens](https://merit-badge.university/merit-badges/geology/guide/req4c3/)**: Choose a 10-specimen collection or a 15-specimen identification path. You will gain either a personal set of labeled materials or strong specimen-recognition practice.
- **[Req 4c4 — Road-Building Materials](https://merit-badge.university/merit-badges/geology/guide/req4c4/)**: Connect common materials in your area to quarrying, crushing, and construction use. You will gain a practical look at geology in everyday infrastructure.
- **[Req 4c5 — Visit or Investigate Resource Use](https://merit-badge.university/merit-badges/geology/guide/req4c5/)**: Choose a field visit or discussion path tying geology to mining, materials, or engineering. You will gain a direct connection between rocks and society.

## How to Approach This Option

This branch works best if you keep labels, notes, and specimens organized from the start. A notebook table with **name**, **rock or mineral**, **origin**, **properties**, and **where found** will help across several pages.

> **Tip**
>
> If you have ever picked up a rock because it looked interesting, this option turns that habit into real geology. Labeling and comparing specimens matters more than collecting a huge number of them.

The first step is learning the rock classes that geologists use as a foundation for almost everything else.
