The English Channel (French: la Manche, Breton: Mor Breizh, Cornish: Mor Bretannek) is an arm of the Atlantic Ocean that separates Great Britain from northern France, and joins the North Sea to the Atlantic. It is about 560 km (350 mi) long and varies in width from 240 km (150 mi) at its widest, to only 34 km (21 mi) in the Strait of Dover. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some 75,000 km2 (29,000 sq mi).
