Geography - Plate Tectonics - Clues to Plate Tectonics

I wanted to produce a resource that looks at the various bits of evidence that shows how Plate Tectonics was derived as a theory, and use them to explain the different features of plate boundaries. I must admit I got a little carried away, hence there being 113 slides. I would suggest that the best approach is to use this presentation in three lessons broken up as follows:

1. Introduction and Constructive Plate Boundaries
2. Destructive Plate Boundaries
3. Conservative Plate Boundaries and Hot Spots

What is covered: Alfred Wegener, Mantle Convection, Polar Wandering, Magnetic Striping, Ophiolite Sequences, Diverging, Converging and Conservative Plate Boundaries and Hot Spot Vulcanism.
