Where do you find headlands and bays?
Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast.
How bays are formed?
When a stretch of coastline is formed from different types of rock, headlands and bays can form. Bands of soft rock such as clay and sand are weaker therefore they can be eroded quickly. This process forms bays. A bay is an inlet of the sea where the land curves inwards, usually with a beach.
How are Tombolos formed?
A tombolo is formed when a spit connects the mainland coast to an island. The process of longshore drift occurs and this moves material along the coastline. Material is pushed up onto beaches at an angle when the swash brings it onto the coastline at a 45 degree angle.
How do headlands and bays change over time?
As the waves erode the coastline, the soft rock will be eroded quicker. This results in the areas of softer rock to retreat, forming bays, whilst the hard rock is eroded slower so will form headlands. Over time, deposition will occur in the bays and so forming beaches.
Where are bays located?
Bays usually occur on oceans, lakes, and gulfs, and generally not on rivers except when there is an artificially enlarged river mouth. An example of a bay at a river’s mouth is New York Bay, at the mouth of the Hudson River.
What do bays look like?
A bay is a body of water partially surrounded by land. A bay is usually smaller and less enclosed than a gulf. The mouth of the bay, where meets the ocean or lake, is typically wider than that of a gulf. Bays can also be called lagoons, sounds, and bights.
How are bays formed?
How are headlands and bays formed along the coastline?
Headlands and bays Cliffs along the coastline do not erode at the same pace. When a stretch of coastline is formed from different types of rock, headlands and bays can form. Bands of soft rock such as clay and sand are weaker therefore they can be eroded quickly.
What are the names of the bays and headlands?
The discordant coastline has been formed into Studland Bay (soft rock), Ballard Point (hard rock), Swanage Bay (soft rock) and Durlston Head (hard rock).
Where are the discordant bays and headlands in Dorset?
Along the coastline of Dorset, there are concordant and discordant coastlines. The concordant coastline runs from west to east along the south coast. The discordant coastline runs from Studland Bay to Durlston Head as the geology changes from clay and sands, to chalk, to clay and sands again to limestone.
What do you call the area next to a headland?
The areas where the soft rock has eroded away, next to the headland, are called bays. Geology is the study of the types of rocks that make up the Earth’s crust. Coastlines where the geology…
