Blakeney Point is a spit that extends along the Norfolk coastline. The shape of the spit is constantly changing, shaped by erosion and deposition. Sand and shingle is moved along the spit carried by the action of the waves, in a process known as longshore drift. On land, the wind blows sand into dunes along the ridge of the split.

Can be used to answer a GCSE style question describing the process of longshore drift or the formation of a spit. Pupils can attempt this by just watching the video and this will then be followed up by the teacher outlining the process to check they have an accurate response.
