Description: As recently as the 1950's, such events as volcanoes and earthquakes which occurred thousands of miles apart were considered by geologists and geophysicists as unrelated activities. Then in the 1960's a revolutionary concept was accepted which connected these events casually on a global scale. The idea is called "plate tectonics". It is now believed that the earth's crust is composed of six major plates upon which the continents are embedded. Moved ever so slowly by hot convection currents from deep within the earth these plates collide, overlap and slide by each other. Where they meet, mountains are upheaved, volcanoes erupt and the ground shudders. Throughout model animation illustrates plate tectonic action.-
