Formation
There are various ways that bays can be created. The largest bays have developed as a result of continental drift. As the super-continent Gondwana broke up along curved and indented fault lines, the continents moved apart and the world's largest bays formed. These include the Gulf of Guinea, Persian Gulf, Gulf of Alaska, Gulf of Mexico and the Bay of Bengal which is the largest bay in the world.
Another way bays are formed is via glacial and river erosion. If formed by glaciers a bay is known as a fjord. Rias are created by rivers and are characterised by more gradual slopes. Most gulf and bays are formed by the folding of the earth's crust as well as coastal erosion due to waves and currents. Currents can make waves more constant, while soft rocks will allow erosion to have a stronger effect. Any hard rock is eroded less quickly, leaving headlands. The Gulf of California is an example of a bay created by the geological process of folding.
