Learn geology basics, identify rock formations, study mining processes, analyze geologic maps, and understand Earth's history to earn this merit badge

## Requirements

  - **4.c** *Rocks, Minerals, and Society* (Do all) Option C—Mineral Resources. Do ALL of the following:
    - **4.c.1** *The Three Rock Classes* Define rock. Discuss the three classes of rocks including their origin and characteristics.
    - **4.c.2** *What Makes a Mineral* Define mineral. Discuss the origin of minerals and their chemical composition and identification properties, including hardness, specific gravity, color, streak, cleavage, luster, and crystal form.
    - **4.c.3** *Collect or Identify Specimens* (Choose 1) Do ONE of the following:
      - **4.c.3.a** *Build a 10-Specimen Collection* Collect 10 different rocks or minerals. Record in a notebook where you obtained (found, bought, traded) each one. Label each specimen, identify its class and origin, determine its chemical composition, and list its physical properties. Share your collection with your counselor.
      - **4.c.3.b** *Identify 15 Specimens* With your counselor's assistance, identify 15 different rocks and minerals. List the name of each specimen, tell whether it is a rock or mineral, and give the name of its class (if it is a rock) or list its identifying physical properties (if it is a mineral).
    - **4.c.4** *Road-Building Materials* List three of the most common road building materials used in your area. Explain how each material is produced and how each is used in road building.
    - **4.c.5** *Visit or Investigate Resource Use* (Choose 1) Do ONE of the following:
      - **4.c.5.a** *Visit a Mine, Quarry, or Pit* With your parent or guardian's and counselor's approval, visit an active mining site, quarry, or sand and gravel pit. Tell your counselor what you learned about the resources extracted from this location and how these resources are used by society.
