Plate Tectonic Notes

Plate Tectonic Notes. Stress is the amount of force per unit area put on a given object. Deformation is the rock changing due to stress. * Three things determine how much stress a rock can handle: composition, temperature and amount of pressure. Types of Stress:.

  2. Stress is the amount of force per unit area put on a given object. Deformation is the rock changing due to stress. *Three things determine how much stress a rock can handle: composition, temperature and amount of pressure. Spring 2006, Pflugerville ISD

  3. Types of Stress: Compression is when two plates collide. (squeezing) Tension is when two plates pulling away from each other. (stretching) Cite: http://www.solaster-mb.org/mb/images/dyrynda-tectonics-1-wl.GIF Spring 2006, Pflugerville ISD

  4. Folding is the bending of rock Anticline are arch-shaped folds. Syncline are trough-shaped folds. Monocline are rocks that have vertical stress and the ends are still horizontal.

  9. Faulting is breaking of rocks Footwall is one side of the rock. Hanging wall is the other side of the rock. A normal fault is when the rocks pull away from each other, the hanging wall moves down. A reverse fault is when rocks are pushed together, the hanging wall is pushed up.

  14. Mountain Building Notes Spring 2006, Pflugerville ISD

  15. Most mountain ranges form where plates collide- convergent boundary. Uplift is the process by which regions of the crust are raised to a higher elevation. Spring 2006, Pflugerville ISD

  17. Folded Mountains are formed when rock layers are squeezed together. Appalachians Fault - Block Mountains are formed when faulting causes large blocks of the crust to drop down. Tetons Volcanic Mountains are formed when molten rocks erupts onto the Earth’s surface. Divergent boundary. Spring 2006, Pflugerville ISD
