Hello, I'm a coastal geomorphologist with a keen interest in the formation and characteristics of various coastal landforms.
Yes, Chesil Beach is indeed considered a tombolo. A tombolo is a narrow, sand or sedimentary deposit that connects an island or a similar landform to the mainland, or two islands to each other. Chesil Beach, located along the coast of Dorset in the United Kingdom, is a remarkable example of this geological feature. It is a pebble ridge that stretches for approximately 18 miles (29 kilometers), linking the Isle of Portland to the mainland.
The formation of Chesil Beach is the result of longshore drift, which is the process by which waves move sediment along the shore. The beach is composed of pebbles that have been rounded and smoothed by the action of the waves over thousands of years. The size of the pebbles tends to decrease in size as you move eastward along the beach, which is indicative of the direction of the longshore drift.

Chesil Beach is 18 miles (28 kilometres) long and, on average, 160 metres wide and rises to 12 metres in height. It is a pebble and shingle tombolo connecting Portland to Abbotsbury and then continuing north-westwards to West Bay near Bridport. It is the largest tombolo in the UK.
