Formative Assessment #1 Part 2. Question 1B. What type of plate tectonic is most suitable for the eastern and western margin of this part of Africa? Note that each margin faces a spreading center. 2B. Using the measuring tool in Google Earth (measuring stick icon on the top tool bar) measure the linear distance across the continental shelf on the western margin (shelf is the light blue area adjacent to 3B. Describe what happens to the continental shelf width to between the Tropic of Capricorn and S 17º 00’ 00” along the eastern margin of southern Africa? 4B. What are two processes that could explain the differences in the continental shelf that you have observed between the two latitudes of the previous question? 5B. Move over to the western margin of southern Africa at the latitude of the Tropic of Capricorn. Zoom into an eye altitude of 300 km and examine the shape of the coastline and the land area along the coast between the Tropic of
