The constant movement of waves at the bottom of cliffs (or any solid structure at the shore) eats away at the area around the crack and renders it weak enough to create sea caves at the bottom. True tombolos are formed by wave refraction and diffraction. Several islands tied together by bars which rise above the water level are called a tombolo cluster. They are deep, long and wide troughs or basins with very steep concave to vertically dropping high walls at its head as well as sides. Those beaches offer diverse opportunities due to the tombolo formation. An example of a tombolo is Chesil Beach, which connects the Isle of Portland to the mainland of the Dorset coast.
