There are seven or eight major plates and several minor plates. The earths crust slides on the molten core, the continental plates drift somewhat freely around and are the cause of a lot of natural phenomenon like mountain-forming and earthquakes due to activity at plate boundaries like subduction or sliding edge to edge
