Scotland is a part of Great Britain. Scotland is the most nothern of the contries that constitute the United Kingdom. Scotland is washed by the Atlantic Ocean in the north-west and by the North Sea in the east. The coastline of Scotland is greatly intended. In many places deep fiords penetrate very far inland. Geographically the territory of Scotland can be divided into three regions: the Nothern Highlands, the Central Lowlands and the Southern Uplands. The Highlands are the highest mountains in the British Isles. Their average height does not exceed 457 m. above sea level though some peaks are much higher, rising over a thousand metres. Ben Nevis is the highest peak in the British Isles, reaches the height of 1343 m. The lowlands are the cradle of the Scotish nation. They are densely populated. The Southern Uplands seldom rise over 579 m. above sea level. It is one of the most sparsely populated distincts in Great Britain.
