  1. Plate Boundaries February 21, 2012

  2. Plate Boundaries • There are three different plate boundaries: Divergent Boundaries Convergent Boundaries Transform Boundaries

  3. Divergent Boundaries • Divergent Boundaries are the boundaries between two plates that are diverging, or moving away from each other. Draw, Color, & Label the Picture

  4. Convergent Boundaries • Convergent Boundaries are the boundaries between two plates that are converging, or moving towards each other. • There are three types of convergent boundaries: • An ocean floor plate collides with a less dense continental plate. • An ocean floor plate collides with another ocean floor plate. • A continental plate collides with another continental plate.

  5. Draw, Color, & Label the Pictures  Oceanic-Continental Oceanic-Oceanic   Continental-Continental

  6. Transform Fault Boundaries • Transform Boundaries are the boundaries between two plates that are sliding horizontally past one another. Draw, Color, & Label the Picture

  7. Effects of Plate Tectonics • Landforms caused by plate tectonics: a. rift valleys (divergent boundaries) b. mountain ranges (continental-continental convergent boundaries) c. volcanoes (oceanic-continental convergent boundaries) d. faults (transform boundaries)

  8. Causes of Plate Tectonics • Convection Current is the driving force of plate tectonics in which hot, plastic-like material from the mantle rises to the lithosphere, moves horizontally, cools, and sinks back to the mantle. • The convection currents provide enough energy to move the plates in the lithosphere.

  9. You will use Chapter 7 in your textbook to answer questions from the science workbook pages 97-98, 1-18. • You need to write the sentence and place your answers in your composition book. • Please label the page in your composition book (Chapter 7 Workbook pages 97-98).
