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: 1. Streak 2. Fluorescence 3. Crystal Structure 4. Cleavage 5. Hardness

3 Mineral Classification 1. Streak: Color of the powder left behind when a mineral is rubbed 2. Fluorescence: Glows under UltraViolet Light 3. Crystal Structure: Atom arrangement in a specific shape 4. Cleavage: Direction of a break in a mineral 5. Hardness: Mohs Hardness Scale

4 Minerals vs. Rocks  Rocks: a solid formation of minerals  3 Major Types: 1. Igneous Rock 2. Sedimentary Rock 3. Metamorphic Rock

5 Igneous Rock  Igneous rock forms when melted rock hardens  2 Types: 1.Intrusive: Cools Inside Earth 2.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.
