Explain the formation of different types of Moraine (7 marks)

A moraine is any material transported and deposited by a glacier, there are many different types of moraine. One type of moraine is medial moraine which is formed where two glaciers meet depositing glacial debris in the centre. A terminal moraine marks the furthest extent of a glacier and is formed when glacial debris is deposited at the snout of a glacier forming a high mound. Lateral moraine appear as embankments at the side of valleys and form when debris falls from the side of a valley and is transported along the edge by a glacier. There is also ground moraine which is deposited at the valley floor, recessional moraine which is a mound of debris that marks the edge of a retreating glacier and push moraine which is a mound of debris that forms when a glacier readvances pushing earlier moraines forward.
