TOPIC 3 and EXTENDED B OBJECTIVES
THE DYNAMIC CRUST
1. Identify 3 types of evidence that suggests there was movement of the Earth's crust in the past.
2E. Name 2 types of earthquake waves.
3E. Using the Earth Science Reference Tables (ESRT), compare the speed of P and S waves
4E. Using the arrival times of P and S waves and the ESRT, determine the epicenter distance of an earthquake.
5E. a. Define origin time.
b. Using the ESRT and given the epicenter distance and the arrival time of the P wave determine the origin time of an earthquake.
6E. Given the P and S wave graph in the ESRT and 3 seismograms, determine the location of an earthquake epicenter.
7. Describe how changes in density of the Earth's interior effect the speed of earthquake waves.
8. Describe evidence from seismic data that suggests the Earth is not a solid body.
9. Compare the Richter and Mercalli scales for measuring the strength of Earthquakes.
10. Describe the possibility of an earthquake occurring in our area.
11E. Using the Inferred Properties of the Earth's Interior chart in the ESRT, describe the changes in density, temperature, and pressure as you move toward the center of the Earth.
12E. Using the ESRT, identify the regions of the Earth's interior and determine the depth at which they occur.
13E. a. State the inferred composition of the Earth's core.
b. Give supporting evidence.
14E. Describe evidence that supports the theory of continental drift.
15E. Describe convection cells within the asthenosphere and how they move the lithospheric plates.
16. Define plate tectonics.
17E. Describe evidence that supports the theory of plate tectonics.
18. Compare the location of earthquakes, volcanoes and mountains to the position of plate boundaries.
19. Describe the movement that occurs along 3 types of plate boundaries:
a. divergent
b. convergent
c. transform
20E. Compare the thickness, composition and age of the continental crust and oceanic crust.
21. On a map of the world, identify locations of frequent crustal activity.
