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. During their formation, tectonic movements created climatic conditions ranging from polar to desert to tropical and a resultant diversity of fossil remains.
Heavy snowfall is not common in the lowlands, but becomes more common with altitude. Braemar experiences an average of 59 snow days per year, while coastal areas have an average of fewer than 10 days. 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
