occurring in the Aragorn Ocean, at what rate was new seafloor being created? (This related to the 1/2 spreading rate). Show your equations and explain where each number came from Rate of formation of Aragorn Ocean crust when it was active mm/y B. Plate Boundaries 1. There are two plate
following types of plate boundaries on Geoworld (Note: the boundary between two plates can vary in type from place to place).

PENDIX C in cross-sections C. Cross-Section Make a schematic cross-section of Geoworld along line A-A' Draw it in the box provided at the bottom of the map on the right sideof page 9. Try to use the cross-section drafting procedures given on p. 515 figure C-3 and p. 516 Figure C-5 in APPENDIX C in your textbook. NOTE: sca level is at 0 kilometers depth on your cross-sections and I made the heightscale different for above and below sea level so that you can fit the entire lithosphere on the cross-section. You can estimate that the continents mostly stick up -1 km above sea level, and rise to -3 km above sea level in the mountains; the ocean basins are flat and 4 km below sea level, except where the spreading center ridges stick up as high as-2 km below sea level, or where the trenches drop to -8 km depth. Label the crust, mantle lithosphere and asthenosphere and show the entire thickness of the lithosphere and part of the asthenosphere below the crust. Estimate thickness of the lithosphere from Figures 26 & 2.21 in your textbook. (Oceanic lithosphere is a bit thinner than continental lithosphere in most places, and thins to nearly O at spreading centers). You will follow this procedure again in the second and third parts of the lab. "Geoworld Plate Tectonics Lab D. Transform Faults There areseveral transform faults in the Elrond Sea. The only parts of these faults that are presently active are the parts between thesegments of the Hobbit Ridge. 1. Using arrows, show the sense of motion on each of the active transform faults on the
