Solution: Lab 5 - The Hazardous Earth
1) 5 pts
Where is the youngest tectonic plate material found in the Atlantic basin?
Full credit is given for answers along the lines of 'down the center of the atlantic basin, running north/south'. Partial credit is given for some but not all of the above, for example, 'in the middle'.
2) 5 pts
Where is the oldest tectonic plate material found in the Atlantic basin? How old is it?
Full credit is given for answers that include both 'along the east coast of North America and the west coast or northern Africa' as well as '154.3 million years old'. Partial credit is given if part, but not all of the previous answer is listed.
3) 5 pts
Where is the youngest tectonic plate material found in the Pacific Ocean?
Full credit is given for answers along the lines of 'in the eastern Pacific off the coast of North and South America'. Partial credit is given for some but not all of the above, for example 'off of the USA'.
4) 5 pts
Where is the oldest tectonic plate material found in the Pacific Ocean?
Full credit is give for answers along the lines of 'in the eastern Pacific near Japan'.
5) 5 pts
What are the locations of the deepest earthquakes?
Full credit is give for noting the following locations: The western Pacific near Indonesia, the western Pacific near Japan, the western coast of South America, and the eastern Medeterranian near Turkey and Syria. Partial credit is given for some but not all of the above.
6) 5 pts
What type of plate boundaries are the deepest earthquakes found near (Note: You may need to turn off the earthquakes to see the type of plate boundary or use p. 9 in your atlas)?
For full credit, the student answers "Convergent boundaries between ocean and continental plates."
7) 5 pts
Are all volcanoes found on or near to plate boundaries? Why do you think that this is the case?
Full credit is given for the following: 'No, not all volcanoes are found near plate boundaries. Some are found in the middle of plates. This is due to mid-plate hot spots. Partial credit is given for some, but not all of the above.
8) 5 pts
For the volcanoes found on plate boundaries, what type of plate boundary are they found on/near? (note: You may need to turn off the earthquakes to see the type of plate boundary or use p. 9 in your atlas)
For full credit, the student answers "Convergent boundaries between ocean and continental plates."
9) 15 pts
What is the azimuth and velocity of the Pacific Plate near Hawaii?
Approximately 67 mm/yr, 15° For full credit the student must note the rate.
10) 15 pts
What is the azimuth and velocity of the North American Plate near Chicago?
Approximately 15 mm/yr, 285° For full credit student must note rate.
11) 10 pts
List the speed, azimuth, north velocity and east velocity for Honolulu, HI. How well do these values match with what you calculated in #7?
67.51 mm/yr, 297.12° For full credit the student compares the results to those that he/she got in #9.
12) 10 pts
List the speed, azimuth, north velocity and east velocity for Chicago, IL. How well do these values match with what you calculated in #8?
15.43 mm/yr, 261.00* For full credit the student compares the results to those that he/she got in #8.
13) 10 pts
Consider the evidence presented in the Jules Verne Voyager. Why do you think that the largest earthquakes are not always the most expensive or kill the most people? Cite evidence from the Jules Verne Voyager.
For full credit the student must cite evidence from the JVV web page and discuss the frequency of quakes and population density.
