1 Recognising coastal features Examine the features/landforms labelled A–N in Figure 1 and on the photographs on this page. On the grid provided on the next page, name each feature and indicate whether it is formed by sea erosion or deposition. Name also one Irish example of each feature. (You may have to research on the internet for some of these examples.)
