Coastal landforms - West Wales
The coastline of West Wales is under constant attack from the prevailing winds travelling over the Atlantic Ocean. Headlands and bays usually form where hard and soft rocks lie, but this coastline is made up entirely of carboniferous limestone. It is the weaknesses and faults of the limestone which determine the landscape. Sea arches, stacks, stumps and caves can all be found along this stretch of coastline.
This clip gives examples of coastal landforms of erosion and deposition, with a nice story about Harlech Castle. While watching the clip, the class could be asked to list any landforms they see, under the headings 'landforms of erosion' and 'landforms of deposition'. There are some nice animations showing how coastal arches form.
