ANSWERS TO WHOLE LOTTA SHAKIN GOING ON (JAN EXAM)

1.Core, mantle, crust
2. from top to bottom: inner core, outer core, mantle, crust
3. upper mantle and crust because they are both solid.
4. tectonic plates
5. because the lower mantle is pasty, and if it moves due to heat changes, it causes the upper mantle to move also.
6. Alfred Wegener
7. Wegener proposed that millions of years ago the continents were all stuck together into one gigantic supercontinent called Pangea. Now they slowly drifted apart because of the movement of tectonic plates.
8.Wegener discovered that the fossils of the same species were found on 2 different, opposing continents. He also realized that the continents fit together like a puzzle.
9. Tectonic plates move towards each other  See image
10. Tectonic plates move away from each other See image
11. When tectonic plates rub side by side against each other. See image
12. The formation of mountains
13. Two tectonic plates collide into each other causing a ripple in the crust.
14. An earthquake is what happens when two tectonic plates suddenly slip past one another. The surface where they slip is called the fault or fault plane
15. The location below the earth’s surface where the earthquake starts is called the location directly above it on the surface of the earth is called the epicenter.
16. seismologist
17. seismograph
18. Richter scale
19. 0-10
20. very low intensity: not felt
21. extremely high intensity : catastrophy
22. converging or diverging
23. As the boundary is separating, magma flows out and turns into colder, dried lava. This lava eventually piles up and causes the bottom of the ocean floor. See video
24. As the tectonic plates are colliding into each other, one of them collapses beneath the other. This causes magma to flow out and pass through the crust. See video
25. magma
26. lava
27. It is the location around the Pacific Ocean where many volcanoes are located.
28. tsunami is a series of waves generated in an ocean by a disturbance such as an earthquake, landslide, volcanic eruption,.. Undersea earthquakes, which typically occur at boundaries between Earth's tectonic plates, cause the water above to be moved up or down.
29. wood, saw, drill, screw, glue, BBQ stick, marker
30. When applying a back and forth force on the base (earthquake) the marker moved back and forth also.
31. To explain what is the intensity of earthquake, by observing the graph that was created.
