The earth is made up of a number of components. At the centre is the solid core which is Nickel - Iron ; around this is a liquid core of the same material. The next part is a liquid called the Mantle, composed of much lighter materials. Finally there is a solid crust, a very thin sheath when compared to the total diameter. The crust is not one solid skin on the Mantle. It is broken into a number of irregular plates . The plates can be large, the pacific plate, or relatively small, some of the Mediterranean plates. The centres of the plates are stable environments while the edges are the earthquake/volcano regions of the earth. These plates move around driven by the convection currents in the mantle.This slide shows a number of the plates and other features of the Indian Ocean. Several mid-ocean ridges are clearly visible delineating the edges of the plates. The plates contain features such as basins and plateaus. the latter are higher regions, some even forming island chains. At the edges of the plates are features such as the Java trench, created where the ocean plate moving east is going under the continental plate.The mantle is plastic. It flows in convection currents from the very hot core to the outer Mantle/crust. These currents cause the crust to move. The currents are continuous and are responsible for all the features on the earth's surface.*******
