About This Lesson
Twenty five slide Slide show about what we think the earth looks like inside. Goes into the structure and the kind of rock that forms different layers. Discusses how the huge plates that make up the earth's surface can move about and how these movements affect landforms on the surface. There is a similar presentation (EARTH'S INNARDS MOVE PLATES...38 slides) that covers all that but goes more into the landforms and how they are created.
