The Isle of Wight is made up of many layers of sedimentary rock, originally deposited in rivers, on floodplains, in lakes and the sea over many millions of years. The layers are formed of fine grained minerals, sands and fossils to form rocks like mudstones, shales, sandstones, siltstones and limestones.
