Peat is made of decomposing plant matter that is often several feet thick. For this to occur, waves must have limited energy, so beaches often form in sheltered areas like bays . Some spits are concave to the sea and are a response to the approach of convexly refracted wave crests.

Through this process material is constantly moved along the coastline. On approaching shallow water near the shores, their speed is reduced and the waves are curved or refracted against the alignment of the coast. Thus, a tombolo acts as a bridge between the coast and an island. If this feature moves in the direction of island and connects it to the mainland then it becomes a tombolo. As waves near an island, they are slowed by the shallow water surrounding it. chemistry past paper A small to medium-sized part of the surface of the earth is called a landform and several related landforms together are known as landscapes.
