8th Grade Integrated Science chapter 14 lesson 3 on the theory of plate tectonics. This lesson covers plate boundaries and the effects of the movement. It includes pictures and definitions of divergent, convergent, transform, collision, and subduction boundaries. There is an explanation of the lithosphere and the asthenosphere including convection currents. This also introduces forces causing plate motion such as basal drag, ridge push, and slab pull.
