  1. Chapter 7 Rocks and Minerals

  2. Minerals vs. Rocks • Mineral: Natural, solid substance that has a specific chemical composition and physical structure • 5 ways to classify MINERALS: • Streak • Fluorescence • Crystal Structure • Cleavage • Hardness

  3. Mineral Classification • Streak: Color of the powder left behind when a mineral is rubbed • Fluorescence: Glows under UltraViolet Light • Crystal Structure: Atom arrangement in a specific shape • Cleavage: Direction of a break in a mineral • Hardness: Mohs Hardness Scale

  4. Minerals vs. Rocks • Rocks: a solid formation of minerals • 3 Major Types: • Igneous Rock • Sedimentary Rock • Metamorphic Rock

  5. Igneous Rock • Igneous rock forms when melted rock hardens • 2 Types: • Intrusive: Cools Inside Earth • Extrusive: Cools Outside Earth

  6. Sedimentary Rock • Sedimentary Rock is formed when layers of sediments bind together.

  7. Metamorphic Rock • Metamorphic Rock is formed when extreme heat and pressure change igneous, sedimentary, or other metamorphic rocks.
