This preview shows page 3 - 5 out of 6 pages.

5. What is the full spreading rate (in mm/y) of the Hobbit Ridge? (i.e., how fast are the Bilbo and Frodo continents moving away from each other)?
6. Using the magnetic anomaly patterns in the Aragorn Ocean, determine when sea floor spreading started to form the Aragorn Ocean crust (remember, spreading is not actively going on now but it was at one time). Spreading Started 130 m.y. ago
4 7. At the time that active sea-floor spreading was occurring in the Aragorn Ocean , at what rate was new sea-floor being created? (Think : is this related to the full spreading rate or the half spreading rate)?
B. Plate Boundaries 1. There are two plate boundaries on the map. You already highlighted one of them in Part 1, A. 1. above. Highlight the other boundary also. 2. Give one example of each of the following types of plate boundaries on Geoworld (Note: the boundary between two plates can vary in type from place to place).
