  • 1. Warm-up, 10.14.2009 Show Mr. Benson what a transverse wave looks like. Next, demonstrate a compressional wave. Montrez M. Benson à ce qu'une onde transversale ressemble. Après, démontrez une vague de compression. Demuestre a Sr. Benson qué una onda transversal parece. Después, demuestre una onda de compresión.
  • 2. Notes, Chapter 12
    • The Earth’s crust is composed of a series of plates (tectonic plates) floating on top of the liquid, molten core of the planet.
    • Mid-ocean ridge : An underwater mountain created by two tectonic plates moving away from each other.
    • Rift Valley: The valley created by two plates moving away from each other. Magma may emerge from these points, cycling crust upwards.

  • 7. Notes, Chapter 12
    • Divergent Boundary: Where two plates are moving away from each other.
    • Convergent Boundary: Where two plates are moving towards each other.
    • Subduction Zone: A kind of convergent zone where two plates come together, one being pushed under the other.
    • Transform Boundary: Where two plates are moving along-side each other. Faults form in these areas.

    • Get with a partner and take out a sheet of paper and a book.
    • Fold, cut, and tape your sheet of paper to model each of the different kinds of plate boundaries.
    • Color the paper to illustrate different levels of elevation. Red = high elevation. Yellow = medium elevation. Blue = low elevation.
    • Look at a map of the world and note the position of mountains.
