Geological complication in the continental collision zones: Note
that significant continental overlaps occur when India, Arabia, and Iberia collide
with the southern edges of Eurasia. The Earth responded to this problem by
shortening, thickening and stacking the crust to form mountain belts. Two
alternatives are offered in this puzzle. In the simpler version, you can just
use the supplied images of Eurasia, India, Arabia, and Iberia with their edges
having pre-cut dents, artificially anticipating the collisions.
Puzzle backboard. When I made this puzzle for my own use,
I wrapped some thick, fuzzy blue cloth around a board to use as the background.
(The fuzziness helps the pieces stay put better.) About the continental shapes. The continental shapes in this "flat earth" depiction were not mathematically derived. Rather, Atwater hand-created them from tracings of a globe, warping them so that they would be flat, recognizable, and would fit together in both their Pangean and present-day configurations. Note that I had to seriously contort Northeastern Eurasia in order to make the rest of the continental fits work on a flat earth. Feedback please: I'd love to hear how this puzzle works for you and any suggestions for how to make the images or description more useful: atwater@geol.ucsb.edu |
