of renewable energy has emerged as an important economic and environmental issue in recent years. Geology and geomorphology ! The geology of Scotland is unusually varied for a country of its size, with a large number of differing geological features. There are three main geographical subdivisions: the Highlands and Islands is a diverse area which lies to the north and west of the Highland Boundary Fault; the Central Lowlands is a rift valley mainly comprising Paleozoic formations; and the Southern Uplands, which lie south of a second fault line, are largely composed of Silurian deposits. The existing bedrock includes very ancient Archean gneiss, metamorphic beds interspersed with granite intrusions created during the Caledonian mountain building period (the Caledonian orogeny), commercially important coal, oil and iron bearing carboniferous deposits and the remains of substantial tertiary volcanoes.
The Southern Uplands are a range of hills almost 200 kilometres (125 mi) long, interspersed with broad valleys. They lie south of a second fault line (the Southern Uplands fault) that runs from the Rhinns of Galloway to Dunbar. The geological foundations largely comprise Silurian deposits laid down some 4500 million years ago. The high point of the Southern Uplands is Merrick with an elevation of 843 m (2,766 ft). The Central Lowlands is a rift valley mainly comprising Paleozoic formations. Many of these sediments have economic significance for it is here that the coal and iron bearing rocks that fuelled Scotland's industrial revolution are to be found. This area has also experienced intense volcanism, Arthur's Seat in Edinburgh being the remnant of a once much larger volcano. This area is relatively low-lying, although even here hills such as the Ochils and Campsie Fells are rarely far from view.
