  1. Earth’s Interior • What is the yellow layer called? • What is the red layer called? • What is the brown layer called? • What is the white layer called? • What circulates within the red layer that is the force behind sea-floor spreading?

  2. Sea-Floor Spreading/Plate Tectonics A • Using the diagram above, answer the following questions: • What type of boundary is shown above at ‘A’? • What process is occurring on either side of ‘A’? • What force is causing this process above to occur? • What ocean floor feature would be formed at letter ‘A’?

  3. Sea-Floor Spreading/Plate Tectonics A Using the diagram above, answer the following questions: • What type of boundary is represented above? • What process is occurring at ‘B’? • What ocean floor feature is formed at ‘A’? B

  4. Sea-Floor Spreading/Plate Tectonics Using the above diagram, answer the following: • What type of boundary is shown above? • What land feature is formed at this boundary?

  5. Faults • What type of fault is this? • What type of stress is associated with this fault?

  6. Faults • What type of fault is this diagram representing? • What type of stress is associated with this fault? • At which boundary are you most likely to find this fault? • What type of stress would you find at a strike-slip fault?

  7. Earthquakes • Point ‘A’ is directly below the epicenter. What is this point called? • Data from at least how many cities needs to be collected in order to find the epicenter of an earthquake? • The first seismic wave to arrive at a seismograph is this wave? A

  8. Volcanoes • Most volcanoes found on the Pacific Ring of Fire are located on __________ zones found at plate boundaries. • Hawaii is an example of a volcano found over a _______ in the middle of a plate.

  9. Volcanoes • This volcano has a wide base, oozes lava, has quiet eruptions and is not very tall. • This volcano is tall and has a narrow base & has explosive eruptions • This volcano alternates between quiet & explosive eruptions and has alternating layers of lava and ash

  10. Volcanoes What is this volcano part? What is this volcano part? What is this volcano part? What is this volcano part? What is this volcano part?
