  1. The Earth in Motion:A Story of Rock Formation Presented by: Jennifer Wickersham Science Instructor Wolfe Middle School Center Line Public Schools April 10, 2010

  2. Activity Time for “A Box of Rocks”

  3. Teacher ‘s Background Information The Earth’s Crust • The outer layer of the earth. • About 22 miles thick (35 km) under the continents. • About 6 miles thick (10 km) thick under the oceans. • The crust is made of ROCK!

  4. What Makes a Rock? • Think of a salad… • Many ingredients (lettuce, carrots, tomatoes, dressing) make a salad. • Individually, the ingredients are ONE type of food.

  5. Rocks are Made of Minerals! • Minerals are the “ingredients” of rocks. Alone, they are minerals…together they are rocks!

  6. What Is a Mineral? • Solid • Inorganic (Not from plants or animals) • Naturally Occurring(Not man-made) • Crystalline Structure(Specific shape) • Definite Chemical Composition(A single substance)

  7. They All Look the Same to Me! Look closely at your sample… • Does it appear to be a single substance? • It is probably a mineral. • Are there many “grains” or clearly more than one substance? • It is probably a rock.

  8. Time for “Stories in Stone”! LHS GEMS Teacher Guide Sessions 6, 7, 8

  9. Teacher ‘s Background Information Plate Tectonics…Briefly • There are three basic types of plate movement: • Converging (moving together) • Diverging (moving apart) • Transforming (moving side by side) • GEMS “Stories in Stone” presents one type of plate movement – continental to oceanic convergence.

  10. Igneous Rock Key: Formed from magma! • Intrusive • Slow cooling inside the crust • Larger than sand-sized crystal grains • Extrusive • Quickly cooling on or above the crust • Smaller than sand sized crystal grains or no crystals

  11. Sedimentary Rock Key: Formed by “leftovers”! • Organic (plants and animals) • Clastic (fragments) • Chemical (dissolved minerals)

  12. Metamorphic Rock Key: Any pre-existing rock changed chemically and physically by heat and pressure! • Foliated • Crystals are flattened in parallel bands • Layering • Non-foliated • No parallel bands • No Layering

  13. The Rock Cycle

  14. Activity After Stories in Stone… Revisit “A Box of Rocks” with the Classification Chart

  15. Extend It! • Journey on the Rock Cycle Activity • Student Power Point – Rocks and Minerals • Make Plate Tectonic Models • Collect Local Rock Samples
