On a concordant coastline weaknesses allow the water to work its way in and eventually erode a large area. Sometimes, idyllic surf sessions depend on a concept called wave refraction. Bays are usually found on oceans, lakes, and gulfs, not rivers, except where an artificially enlarged river mouth is present.

Alternating layers of hard and soft rock allow the sea to erode the soft rock faster, forming a bay but leaving hard rock sticking out, known as a headland. As landforms of erosion, cliffs are created when natural weather events such as wind, rain or waves break tiny particles and pieces of soft rocks and minerals, called sediment , away from harder rocks. Deposits of sediment are the leading cause behind the formation of beaches. Save my name, email, and website in this browser for the next time I comment. Differential erosion creates headlands and bays, in which rocks along the coast are formed in alternating bands of various rock types, such as sandstone and clay, that meet the coast at right angles. c. wind blowing across the water's surface.

The Bay of Bengal in India, the worlds largest bay, is actually larger than the worlds largest gulf. A tombolo is formed when a spit connects the mainland coast to an island. The primary characteristics of this landform are low-wave energy, strong offshore sediment influence, and a full continental shelf. Bays are the areas where soft rock has eroded away next to the headland. A headland may extend a quarter mile out to sea. Softer rocks wear away faster than harder ones. Red and green chert in the Marin Headlands Terrane of the Franciscan Complex was deposited from about 200 million years ago to 100 million years ago. Headlands are formed on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Barrier islands, barrier spits, beaches, tombolos, and dunes are typical features of the sandy coast landforms. Erosion characterizes these high-energy environments, which are typically located on active margins with narrow continental shelves (on account of subduction). In Geography, the erosion of headlands in developing the sequence of cave to stumps is well developed, but how is it extended at the Post 16 .

The sandy coast landforms, mostly located in the passive margins, have extremely dynamic environments that are subject to rapid and severe changes. How does wave refraction affect headlands and bays? Coastlines are littered with the evidence of erosion and the power of the sea. the bits that are sticking out in the sea are called the headlands.
