How are the two mountain ranges related, if at all? Analysis of Geoworld in the Past B. What type of plate tectonic event do they probably represent? C. While the Elrond Sea has been opening, the Aragorn Ocean has been closing. Assuming that (1) no sea-floor spread has taken place in the Aragorn Ocean for at least 65 million years, and (2) subduction has been occurring for at least 65 million years, how wide was the Aragorn Ocean along A-A'at the time spreading started in the Elrond Sea? Use the Sauron Trench as the western boundary of the Aragorn Ocean. Show your equations and explain where each number came from.Width of Aragorn Ocean along A-A' at the time spreading started in the Elrond Sea = D.Move the Bilbo/Frodo supercontinent back to its original position at the time that spreading started in the Elrond Sea. You have now reconstructed the complete plate tectonic picture of the Geoworld planet at the time when spreading started in the Elrond Sea. Tape or glue the cut-out pieces onto a blank page, carefully placing them in their correct positions for the reconstruction. Label the following: 1. Bilbo/Frodo supercontinent 3. Sauron Trench 2. Aragorn Ocean 4. Galadriel Islands E.Make a schematic cross-section of your past reconstruction of Geoworld along A-A'. Show the entire thickness of the lithosphere and part of the asthenosphere.

8 “Geoworld” Plate Tectonics Lab A. When will the Bilbo Continent and the Sauron Trench first collide? Show your equations and explain where each number came from.Analysis of the Future State of Geoworld
B. How wide will the Elrond Sea be at that time? Show your equations and explain where each number came from.
km C.Cut out pieces as needed from the map on page 13 and use them to reconstruct the configuration of the plates for the time of the first collision of the Bilbo continent with the Sauron trench Tape or glue the cut-out pieces onto a blank page, carefully placing them in their correct positions for the reconstruction. Label the following: 1. Galadriel Islands 4. Bilbo Continent 7. Frodo Continent 2. Sauron Trench 5. Hobbit Ridge 3. Aragorn Ocean 6. Elrond Sea D.Make a schematic cross-section of your prediction for the future state of Geoworld along A-A'. Show the entire thickness of the lithosphere and part of the asthenosphere.
