1. Plate Tectonics Review http://www.mymapman.com/images/Plate%20Tectonics-Wenschow800p.jpg

2. This layer of the earth floats on a lower fluid layer. The Lithosophere

3. * Transform Boundary * Divergent Boundary * Convergent Boundary Name the three kinds of Plate Boundaries

4. What are the three types of seismic waves? 1) Primary Waves (P waves) 2) Secondary Waves (S waves) 3) Surface Waves

5. Define Radiation And give an example Radiation is the transfer of heat through EMPTY SPACE.

6. What should you do if you are outside when an earthquake occurs? Move to open area Stay away from trees/ buildings Stay away from power lines Sit down

7. What are 3 pieces of evidence of Continental Drift? 1. Continents fit together like a puzzle. 2. Dinosaur fossils in S. America and Africa. 3. Tropical plant fossils in the Arctic

8. Explain a Transform Boundary A transform boundary is when plates slip past each other in opposite directions http://www.visionlearning.com/library/modules/mid66/Image/VLObject-3571-060216020229.jpg

9. If it took 50 sec. for the S wave to arrive, how far away is the epicenter? About 490 km away http://www.visionlearning.com/library/modules/mid66/Image/VLObject-3571-060216020229.jpg

10. Explain a Divergent Boundary A divergent boundary is when plates move away from each other http://www.indiana.edu/~geol116/week7/week7.htm

11. Describe an Earthquake. An earthquake is a violent shaking of the Earth's crust, due to movement of rock beneath the Earth's surface.

12. Stress that pushes rock in two opposite, horizontal directions Describe Shearing Stress http://www.msnucleus.org/membership/html/k-6/pt/plate/5/images/transform.gif

13. What are two things that you can do to your house to make it “earthquake safe?” Bolt shelves to wall. Remove hanging items from wall above bed Bolt house to foundation Secure chimney to house

14. Explain Convection Currents and give an example Convection Currents is the movement of heat through a fluid (liquids or gases).

15. Describe Compressional Stress Stress that squeezes rock until it folds or breaks. This occurs when plates collide with each other. http://earthquake.usgs.gov/learning/glossary.php?term=compressional%20stress

16. How fast are the continents moving? a. 5 feet per year b. 1 foot per year c. 2-3 cm year The continents move about 2.5 cm per year

17. Mountains form from Compressional stresses (folding) and from Faults (uplifting a block of rock between two normal faults) What are the two ways that mountains are formed?

18. Seismograph What is used to record the ground's movement during an earthquake?

19. What is an example of a destructive force that shapes the earth? Earthquakes, weathering, erosion, flooding, glacier movement

20. Describe Tensional Stress A force that pulls on the crust, stretching rock so that it becomes thinner in the middle. http://www.eoearth.org/upload/thumb/4/4e/Syncline_fold_diagram.gif/250px-Syncline_fold_diagram.gif

21. Separate sections of the lithosphere are called...? Plates

22. Define Conduction and give and example Conduction is the transfer of heat by DIRECT CONTACT.

23. Draw a picture of seafloor spreading

24. Label #1, 2, 3, 4 1. 2. 4. 3.

25. Which two scales measure the strength of an earthquake? And, which scale is most accurate? The Richter Scale and the Moment Magnitude Scale are used to measure earthquakes. The Moment Magnitude Scale is more accurate.

26. Explain a Convergent Boundary A convergent boundary is when plates move towards each other http://stloe.most.go.th/html/lo_index/LOcanada4/403/html/3_en.htm

27. What is the difference between the focus and the epicenter of an earthquake? The focus is deep in the Earth where the earthquake originates. The epicenter is the location on the surface of the earth, directly above the focus

28. What should you do if you are inside when an earthquake occurs? Get under a sturdy object like a table. Sit against an inside wall and protect neck and head

29. Describe Faults Breaks in the Earth's crust where rocks have slipped past each other

30. What type of rock makes up the oceanic crust? Basalt

31. What drives the plate movement? How is the lithosphere able to float around? Convection Currents in the Asthenosphere move the plate above

32. Draw a picture of subduction

33. What type of rock makes up the continental crust? Granite

34. What is the difference between the inner core and the outer core of the Earth? The inner core is solid nickel & iron The outer core is liquid nickel & iron

35. What is a Tsunami? A Tsunami is a large wave formed by an earthquake in the ocean floor. Wave grows once it reaches the shallow shore. Can be 10 stories high

36. Label #1, 2, 1. 2. Lithosphere Asthenosphere
