6. Results of plate movement
(Amazing Earth Notes, Origins DVD, Web Quests, Power points, and How Have Continents Moved?)
a. How continents have been organized in the past
b. How continents will be positioned in the future
c. Results or things influenced by plate tectonics:

Appalachians and Himalayas
2. Volcanic Mountains or Volcanic Island Arcs
3. Ocean Currents
4. Evolution/fossils
5. Mineral deposits
6. Earthquakes
