WebTheory of Plate Tectonics • Plate Tectonics • Centuries of observations have concluded that the Earth ʼ s composition and structure are not random • Pattern recognition: earthquakes occur where mountains rise & volcanoes explode • Composite of ideas that explain the observed motion of Earth ʼ s lithosphere thru mechanisms of subduction & sea-floor … WebSurface waves follow P and S waves. They travel along the surface of the earth and thus cause the most damage. Surface waves can be characterized as Love waves, which are faster and move the ground from side to side, and Rayleigh waves, which roll like waves on the surface of oceans and lakes. open the file manager
