Are you teaching about the theory of continental drift and the evidence to support this theory? This 18 slide PowerPoint begins by describing the structure of the earth including the oceanic and continental crust, mantle, lithosphere, and asthenosphere. It then discusses the Theory of continental Drift proposed by Alfred Wegener. Evidence to support the theory is also given. It concludes by recounting why the continental plates move with convection currents.
I use this PowerPoint with a note taking guide that may be purchased separately. The note taking guide follows the PowerPoint and helps keep students engaged by filling in blanks while viewing and discussing the slides.
