Chesil Beach is 18 miles (28 kilometres) long and on average is 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.
The pebbles are graded in size from fist-sized near Portland to pea-sized at Bridport.
The pebbles are mainly a mix of flint and chert, with some quartzite pebbles from Buddleigh Salterton.
The origin of the beach continues to be argued over with some proposing it is actually two beaches.
The stretch from West Bay to Abbotsbury appears to have different characteristics to the stretch from Abbotsbury to Portland.
