ABSTRACT
In terms of natural, as opposed to political geography, it can be argued that Britain is marked by great contrasts but few extremes. Its highest mountain is Ben Nevis (4,408 ft or 1,344 m) in Scotland; its longest river is the Severn (220 miles or 354 km), which rises in central Wales but also wanders as far east as Gloucester in England. Its largest lake is Lough Neagh (148 sq miles or 383 sq km) in Northern Ireland. Officially, the mainland
stretches from Dunnet Head in the north of Scotland to Lizard Point in Cornwall, but most people will describe Britain as running from the famous names of Land’s End, in the south, to John O’Groat’s.
