Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula.
The more significant ones have been tagged with an *. Headlands around the British coast are most commonly named as 'point', 'ness' or 'head' though 'trwyn' (nose), 'penrhyn' (peninsula) and 'pen' (head) are common in Wales as is 'rubha' in western Scotland. Below is a list of headlands of the United Kingdom sorted by county.
This list catalogues about 400 of the coastal landforms of the island including bays, estuaries, harbours, headlands, and many others. [3] [4] [5] Most offshore features such as islands, stags , and rocks are omitted but are presented at List of islands of Ireland. A list of beaches is available at List of beaches in Ireland.
The differing resistance to erosion leads to the formation of headlands and bays. A hard rock type such as granite is resistant to erosion and creates a promontory whilst a softer rock type such as the clays of Bagshot Beds is easily eroded creating a bay.
The coastline of the United Kingdom is formed by a variety of natural features including islands, bays, headlands and peninsulas. It consists of the coastline of the island of Great Britain, the north-east coast of the island of Ireland, as well as many much smaller islands. Much of the coastline is accessible and quite varied in geography and ...
The bay covers somewhere between 400 and 1,600 square miles (1,000–4,000 km 2), depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. [ 4 ] [ 5 ] [ 6 ] The main part of the bay measures three to twelve miles (5–19 km) wide east-to-west and somewhere between 48 miles (77 km) 1 ...

Bays also form through coastal erosion by rivers and glaciers. [7] A bay formed by a glacier is a fjord. Rias are created by rivers and are characterised by more gradual slopes. Deposits of softer rocks erode more rapidly, forming bays, while harder rocks erode less quickly, leaving headlands.
