In places such as Worbarrow Bay and St Oswald's Bay, lateral widening of coves led to them joining into a single bay, with remnants of the outer Portland left as a line of stumps parallel to the coast, e.g. Large particles like boulders are pushed along the bottom of the river bed/sea by the force of the water. The image below (figure 2) is taken at Durlston Head, which shows the bay (yellow) and the headland (red).

The coast, also known as the coastline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the ocean or a lake. As our Earth warms, glaciers melt, causing the sea level to rise. Over time, waves beating against the shore will wear it down (or erode it). 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 . A case study of a sparsely populated area Himalayan Mountains, A case study of a densely populated area Greater London. The differing resistance to erosion leads to the formation of headlands and bays. In 1982, the United Nations held a Convention on the Law of the Sea (UNCLAS), where maritime (sea) boundaries were established. Concordant coastlines - A coastline parallel to the land structures which form the margin of an ocean basin. The following are facts about destructive waves. Concordant coastlines are also called 'concordant longitudinal' or 'Pacific type' coastlines. Or in other words, these types of coastlines have the same type of rock all along its length.

Discordant coastlines are characterised by different bands of rocks running perpendicular to the coast. These coastlines may lead to the formation of either Dalmatia landforms or Haffs (also called lagoons). A concordant coastline produced by the geological structure of folds parallel to the coast. Key Question: What are the different landforms of the Jurassic Coast? They have a mainly circular orbit, a .. gradient. Wave refraction involves waves breaking onto an irregularly shaped coastline, e.g. The relatively gentle profile of the beach with a steep ridge at the top of the beach means that the backwash soaks into the sand or slowly drains away. (For example the east of the Dorset coast) How Geology affects the coast . Consequently headlands and bays form along discordant coastlines and whilst headlands remain exposed to the force of the waves, bays are sheltered. Many of our major cities have developed along oceanic coasts as well: think of New York City, Tokyo, Istanbul, Dubai, Hong Kong, and Copenhagen, just to name a few! They are, for the time being, out of reach of the current wave action and will therefore not be affected by them. The differing resistance to erosion leads to the formation of headlands and bays.
