  1. Introduction to Physical ScienceMonday, Wednesday, ThursdayTom Burbinetomburbine@astro.umass.edu

  2. Schedule • November 29 - • December 1 - • December 2 – Quiz #8 • December 6 - • December 7 (1:30 pm) (optional) – Field Trip to look at rocks • Will replace your lowest Lab score • December 8 - • December 9 – Presentations • 5-10 minutes • On how you would teach something you learned in class to your students • December 13 – Final • Covers everything from midterm • Can bring in one sheet of paper with anything you wanted written on it

  3. Rocks on the Surface • If you can see rocks on the surface that comes from the interior, you can study them

  4. Rocks can deform and flow • Easier for rock to deform and flow when it is warmer

  5. Lithosphere • Lithosphere is a planet’s outer layer of cool and relatively rigid rock • Asthenosphere is the region in the upper mantle characterized by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere

  6. Heating of Planet

  7. How does the planetary interior cool off? • Heat is transported outward

  8. How does the planetary interior cool off?

  9. Magnetic storms can also perturb Earth’s external magnetic field…

  10. Plate Tectonics • Plate tectonics describes the large scale motions of Earth's lithosphere.

  11. Pangea • Pangea - One large supercontinent http://geology.csupomona.edu/drjessey/class/Gsc101/pangea.gif

  12. Principles of Plate Tectonics • 1. The surface of the Earth is composed of lithospheric plates that are in constant motion. • The plates move in response to plastic flow in the athenosphere. • Motion in the asthenosphere is caused by convection driven by the Earth’s internal heat. • The internal heat comes from radioactive decay and the latent heat from the Earth’s formation.

  13. Three Types of Plate Tectonic Boundaries • Divergent – plates move apart, space is filled with molten magma • Convergent – plates collide • Transform – plates slide horizontally past each other

  14. Divergent plate boundary

  15. Magnetic stripes on Mars

  16. Convergent Plate Boundary

  17. Hot spots

  18. Transform Boundaries

  19. Any Questions?
