Transcript of "Earth Science 9 2"

  1. 1. Plate Tectonics 9.2<br />
  2. 2. Plate Tectonics <br />The theory that proposes that Earth’s outer shell consists of individual plates that interact in various ways and thereby produce earthquakes, volcanoes, mountains, and the crust itself.<br />
  3. 3. Plate<br />One of numerous rigid sections of the lithosphere that moves as a unit over the material of the asthenosphere.<br />
  4. 4. Divergent Boundary <br />A region where the rigid plates are moving apart, typified by the oceanic ridges. <br />
  5. 5. Covergent Boundary <br />A boundary in which two plates moves together.<br />
  6. 6. Transform Fault Boundary<br />A boundary in which two plates slide past each other without creating or destroying lithosphere.<br />
  7. 7. Key Concept<br />What is the theory of plate tectonics?<br />According to the theory of plate tectonics, the uppermost mantle, along with the overlaying crust, behaves as a strong, rigid layer. This layer is known as the lithosphere.<br />
  8. 8. Key Concept<br />What are lithospheric plates?<br />They are plates within the lithosphere that are continually moving and changes shape/size.<br />
  9. 9. Key Concept<br />What are the three types of plate boundaries? <br />The three types of boundaries are convergent, divergent, and transform fault boundaries. <br />
