The earth's crust is made up of 12 rigid tectonic plates that are 60-200 km thick. The document discusses plate boundaries and provides examples of the San Andreas fault in California and the 1964 earthquake in Turnagain Heights, Alaska that resulted from plate tectonic activity. Different types of boundaries like strike-slip, thrust, and normal are shown in diagrams.
