1.There are three plate boundaries on the map. You already highlighted one of them inPart 1, A. 1. above. Highlight the convergent boundary also.2.How many lithospheric plates are there in all?C. Transform FaultsThere are several transform faults in the Elrond Sea. The only parts of these faults that arepresently activeare the parts between the segments of the Hobbit Ridge. 1.Using arrows show the sense of motion on each of the active transform faults on themap.D. Earthquakes1. Describe three distinct places on the planet of Geoworld where you would expect largenumbers of earthquakes.a.b.c.2. The vast majority of earthquakes are caused by movement on faults. What types offaults would you expect at each location you described above (thrust, normal, strike-slip)? a.b.c.3. For each location described above, record whether the earthquakes will have deep fociand/or shallow foci.a.b.c.

E. The Origin of the Volcanic Islands1. The Galadriel Islands, Gandalf Islands and Gollum Island are all made of volcanicrocks. What are the differences in tectonic origin among these three groups ofislands? 2.What type of volcanoes would you expect Galadriel Islands to be and why? Howabout the Gollum Islands?F. Hot-spots and Absolute Movement Rates1. Absolute motion of the Aragorn Ocean and the Bilbo ContinentNotice the Gandalf Islands. They are analogous to the Hawaiian Islands on Earth.They form a linear chain that originated by the migration of the plate over a mantle hotspot. Mantle hot spots are assumed to be fixed relative to the center of the planetAll of the Gandalf islands are volcanic in origin but the easternmost and largestisland--which is sitting directly over the hot spot--is the only one with active volcanoes onit. The rocks on the westernmost island have been dated by radiometric methods at 32 m.y.Measure the distance between the centers of the westernmost and easternmostGandalf islands and use this information to calculate the absolute movement rate (inmm/y) of the Aragorn Ocean (and the Bilbo Continent, which is connected to it).Show your equations and explain where you got each of your numbers..
