The Earth’s structure is made up of six layers. The top layer is the crust. The crust took on a solid form billions of years ago. It is broken up into huge, very thick 'plates'. The plates then rest upon a rocky mantle. Shifting of the plates can cause major alterations to the Earth’s surface by way of events such as earthquakes and tsunamis.
