Moraines are accumulations of mud and rocks that have collapsed onto the glacier surface. These deposits composed of mud and rocks range in size from fine powdery sediment to big rocks and boulders. Kettle Moraine, Harbour Hill Moraine, Long Island, Cape Ann Peninsula in the USA are some of the famous moraines in the world. The types of moraine that form landforms are Lateral, Medial, Ground and Terminal moraines. Terminal moraines are formed at the foot of the glacier and they mark the maximum advance of the glacier whereas lateral moraines are formed at the side of the ice flow. When two glaciers meet it leads to the formation of median moraines. There are two processes through which moraines are formed namely active process and passive process.
