Thank you! 1 Purpose: To better understand the principles of the plate tectonics theory by applying them to the past, present and future analysis of a theoretical planet. Reading Assignment: Any passages on plate tectonics in your textbook. Introduction During this lab exercise, we will analyze the plate tectonics of part of a mythical planet called Geoworld; a tectonic map of the area is shown on p. 9. Geoworld has a plate tectonics system just like ours on Earth, only Geoworld is flat instead of spherical. In answering the questions below, you may assume that the movement rates for plates (both relative and absolute) are constant throughout the time between your past and future reconstructions (they were, however, quite different at one time - see Part 1, A., questions 6 and 7). All questions are in bold face. Please put your answers in any blanks provided.
