  1. Story in the Rocks By: Riley Fanning, Maria Ezzell, Robbie Himebaugh

  2. Rock Cycle/Types • The Rock Cycle is the formation, breakdown, and reformation of rocks. • The 3 types of rocks include Igneous, Sedimentary, and Metamorphic.

  3. Igneous Rocks • A rock that forms after magma/lava cools.

  4. Metamorphic Rocks • A rock that forms under a lot of pressure and heat.

  5. Sedimentary Rocks • A rock that forms from compacted pieces of sediment.

  6. Weathering • Weathering is two process (chemical and physical) that often work in concert to decompose rocks. • Chemical Weathering – involves a chemical change in at least some of the minerals within a rock. • Physical Weathering – physically breaking rocks into fragments.

  7. Erosion • Erosion is simple movement to a slope due to gravity. (Mass Wasting) • Sheet Erosion – a type of soil erosion on sloping farmland, in which rain washes the top layer of soil off. Sheet Erosion

  8. Geologic Time Scale • The Geologic Time Scale is a chart that shows the eons, eras, epochs, and pivotal events, that happened in that time period.

  9. Fossils • A Fossil is an imprint that shows bones, shells, animals etc. on rocks.

  10. Superposition • The Law of Superposition is the bottom layer of rocks are older than the top layer of rocks.
