The geography of Scotland is highly varied, from rural lowlands to barren uplands, and from large cities to uninhabited islands. Located in north-west Europe, Scotland comprises the northern one third of the island of Great Britain and over 790 surrounding islands and archipelagoes.
Scotland's only land border is with England, which runs for 96 kilometres (60 mi) in a northeasterly direction from the Solway Firth in the west to the North Sea on the east coast. Separated by the North Channel, the island of Ireland lies 30 kilometres (20 mi) from the southwest tip of the Scottish mainland. Norway is located 305 kilometres (190 mi) to the northeast of Scotland across the North Sea. The Atlantic Ocean, which fringes the coastline of western and northern Scotland and its islands, influences the temperate, maritime climate of the country.
The topography of Scotland is distinguished by the Highland Boundary Fault a geological rock fracture which traverses the Scottish mainland from Helensburgh to Stonehaven. The faultline separates two distinctively different physiographic regions; namely the Highlands to the north and west and the lowlands to the south and east. The more rugged Highland region contains the majority of Scotland's mountainous terrain, including the highest peak, Ben Nevis. Lowland areas, in the southern part of Scotland, are flatter and home to most of the population, especially the narrow waist of land between the Firth of Clyde and the Firth of Forth known as the Central Belt. Glasgow is the largest city in Scotland, although Edinburgh is the capital and political centre of the country.
An abundance of natural resources such as coal, iron and zinc contributed significantly to the industrial growth of Scotland during the 19th and early 20th centuries. Today, energy is a major component of Scotland's economy. Whilst Scotland is the largest producer of petroleum in the European Union, the production potential of renewable energy has emerged as an important economic and environmental issue in recent years.
Geology and geomorphology
The land area of Scotland is 78 772 kmē (30,414 square miles), roughly 30% of the area of the United Kingdom (UK). The mainland of Scotland has 9 911 km (6158 miles) of coastline.
The geomorphology of Scotland was formed by the action of tectonic plates, and subsequent erosion arising from glaciation. The major division of Scotland is the Highland Boundary Fault, which separates the land into 'highland' to the north and west, and 'lowland' to the south and east. The Highlands of Scotland are largely mountainous, and form the highest ground in the UK: they are bisected by the Great Glen into the Grampian Mountains to the southeast and the Northwest Highlands. The Scottish Lowlands can be further subdivided into the Southern Uplands, an area of rolling farmland and high moorland, and the lowland farmland of the Central Belt and eastern Scotland.
Scotland has an incomparable variety of geology for an area of its size. It is also the origin of many significant discoveries and important figures in the development of the science.
The oldest rocks of Scotland are the Lewisian gneisses, which were laid down in the Precambrian period, up to 3,000 Ma (Mega annum or million years ago). They are among the oldest rocks in the world. During the Precambrian, the Torridonian sandstones and the Moine were also laid down. Further sedimentary deposits were formed through the Cambrian period, some of which metamorphosed into the Dalradian series. The area which would become Scotland was at this time close to the south pole.
During the Silurian period (439-409 Ma), the area which became Scotland was part of the continent of Laurentia. Across the Iapetus ocean to the south, was the continent of Baltica. The two continents gradually collided, joining Scotland to the area which would become England and Europe. This event is known as the Caledonian Orogeny, and the Highland Boundary Fault marks this stitching together of continents. Silurian rocks form the Southern Uplands of Scotland, which was pushed up from the seabed during the collision. The highlands were also pushed up as a result of this collision, and may have been as high as the modern-day Alps at this time. The Old Red Sandstones were laid down in low-lying areas during this period. Volcanic activity occurred across Scotland as a result of the collision of the tectonic plates, with volcanoes in southern Scotland, and magma chambers in the north, which today form the granite mountains such as the Cairngorms.
During the Carboniferous period (363-290 Ma), Scotland lay close to the equator. Several changes in sea level occurred during this time. The coal deposits of Lanarkshire, and further sedimentary deposits, date from this time. More volcanic activity formed Arthur's Seat in Edinburgh, among other hills. By the Triassic, Scotland was a desert, the origin of large sandstone outcrops of the southwest. Although large deposits of Cretaceous rocks would have been laid down over Scotland, these have not survived erosion, as have the chalks of England.
By the Tertiary period, the tectonic plates were again moving, separating into modern-day North America and Europe with the creation of the Atlantic Ocean. The split occurred to the west of Scotland, leaving a chain of former volcanic sites through the Hebrides, including Skye and St. Kilda. This was the last period of rock formation in Scotland. Since then, several ice ages have shaped the land through glacial erosion, creating u-shaped valleys and depositing boulder clays. In the present day, Scotland continues to move slowly north.
Climate
The climate of Scotland is temperate and very changeable, but rarely extreme. Scotland is warmed by the North Atlantic Drift and given the northerly location of the country, experiences much milder conditions than areas on similar latitudes, such as Labrador in Canada—where icebergs are a common feature in winter.
Average temperatures are lower than in the rest of Great Britain, with the coldest ever UK temperature of -27.2 °C recorded at Braemar in the Grampian Mountains, on January 10, 1982 and also at Altnaharra, Highland, on December 30, 1995. Winter maximums average 5.0 to 5.7 °C, with summer maximums averaging 14.9 to 16.9 °C. Western coastal areas of Scotland are warmer than the east and inland areas, due to the influence of the Atlantic currents, and the colder surface temperatures of the North Sea. The highest temperature recorded was 32.9°C at Greycrook in the Scottish Borders on August 9 2003.
Rainfall totals vary widely across Scotland—the western highlands of Scotland are one of the wettest places in the UK with annual rainfall up to 4577 mm. Due to the mountainous topography of the western Highlands, this type of precipitation is orographic in nature, with the warm, wet air forced to rise on contact with the mountainous coast, where it consequently, cools and condenses, forming clouds. In comparison, much of eastern Scotland receives less than 870 mm annually; lying in the rain shadow of the western uplands. Snowfall is less common in the lowlands, but becomes more common with altitude. Parts of the Highlands have an average of 36 to 105 snow days per year, while some western coastal areas have between 0 and 6 days with snow a year.
The Hebridean island of Tiree received a total of 329 hours of sunshine in May 1946 and again in May 1975, the highest number of sunshine hours ever recorded in one month in Scotland. On the longest day of the year there is no complete darkness over the northern isles of Scotland. Lerwick, in Shetland, has four hours more daylight at midsummer than London, although this is reversed in midwinter. Annual average sunshine totals vary from as little as 711–1140 hours in the Highlands and the north-west up to 1471–1540 hours on the extreme eastern and south-western coasts.
In common with the rest of the British Isles, wind prevails from the south-west, bringing warm, wet and unstable air from the Atlantic. The windiest areas of Scotland are in the north and west, with parts of the Outer Hebrides, Orkney and Shetland experiencing over 30 days with gales per year. Vigorous Atlantic depressions, also known as European windstorms, are a common feature of the autumn and winter in Scotland.
Physical geography
Extreme points
The extreme points of the Scottish mainland are:
It is often yet incorrectly stated that John o' Groats is the most northerly point of mainland Scotland. The pre-Union phrase "John o' Groats to Maidenkirk" was the Scottish equivalent of the British Land's End to John o' Groats.
The extreme points of Scotland, including outlying islands, are:
The geographical centre of Scotland lies a few miles from the village of Newtonmore in Badenoch, far to the north of the modern population heartlands.
Mountains
Scotland contains the most mountainous terrain in Great Britain. Much of the highest uplands lie to the north and west of the Highland Boundary Fault in the Northwest Highlands and Grampian ranges. The Cuillin on the Isle of Skye, represents a major mountain range that is not located on the Scottish mainland. Located at the western end of the Grampian Mountains, at an altitude of 1344 m (4409 ft), Ben Nevis is the highest mountain in Scotland and Great Britain. Ben Macdui and Braeriach are, respectively, the second and third tallest peaks in Scotland.
Mountains in Scotland are categorised by their height. Peaks over 3000 ft (914.4 m) are known as Munros. There are 284 Munros in Scotland, all within the Highlands. Corbetts are peaks with an altitude of between 2500 and 3000 ft (762 and 914.4 m), with a relative height of at least 500 ft (152.4 m). The classification of peaks in Scotland is kept under periodic review by the Scottish Mountaineering Club.
The southern and eastern parts of Scotland are referred to as the Scottish Lowlands which contain significant ranges of hills, although at much lower altitudes than those found in the Highlands. The Southern Uplands form a continuous belt from Galloway in the west to Berwickshire in the east. The Pentland Hills and the Lammermuir Hills are several of the local ranges which make up the Southern Uplands. The Sidlaw Hills to the north of Dundee, the Ochils to the east of Stirling and the Campsie Fells to the north of Glasgow constitute important upland ranges in Central Scotland.
In addition to the main upland zones in southern Scotland there are many individual hills, not part of any range. Several of these elevations are volcanic in origin and are known by the Scots word Law, meaning hill. North Berwick Law and Traprain Law are two examples of these extinct volcanic outliers.
Coastline
Mainland Scotland has 9, 911 km (6,158 miles) of coastline. Including the numerous islands, this increases to some 16, 490 km (10,246 miles). The west coast in particular is heavily indented, with long promontories separated by fjordlike sea lochs. The east coast is more regular, with a series of large estuarine inlets, or firths, and long sandy beaches, for example at Aberdeen. Much of the Scottish coastline consists of a machair formation, a dune pasture land formed as sea levels subsided.
The east coast has several significant estuaries and other nature reserves including the Ythan Estuary and Fowlsheugh, both of which have been designated as Important Bird Areas.
Firths of Scotland include the Solway Firth, Firth of Clyde, and Firth of Lorne on the west coast, and the Cromarty Firth, Moray Firth, Firth of Tay, and Firth of Forth on the east coast. The Pentland Firth is not an inlet, but the strait that separates the Orkney Isles from the mainland.
Major sea lochs include Loch Fyne, Loch Long, Loch Ryan, Loch Linnhe, Loch Torridon, Loch Ewe, and on the Isle of Lewis, Loch Seaforth.
Islands
Scotland has some 790 islands, most of which are located off the northern and western coast of the country. The northern and western islands of Scotland can be found in three main groups: Shetland, Orkney and the Hebrides which can be divided into the Inner Hebrides and the Outer Hebrides. Shetland and Orkney, together with Fair Isle and Stroma are referred to as the Northern Isles. With a total land area of 2225 kmē (859 milesē) Lewis and Harris is the largest island surrounding Scotland.
Many of these offshore islands are swept by strong tides, and the Corryvreckan tide race between Scarba and Jura is one of the largest whirlpools in the world. Other strong tides are to be found in the Pentland Firth between mainland Scotland and Orkney, and the Grey Dog between Scarba and Lunga. There are also numerous clusters of islands in the Firth of Forth and the Firth of Clyde and in freshwater lochs such as Loch Lomond and Loch Maree. Outlying islands include St Kilda and Rockall the status of which is disputed.
Scotland's islands have a varied topography. Mull, Skye and Arran are noted for their mountainous terrain, whilst Tiree, Coll and most of the Shetland group are flat or low lying. Striking topographical differences can be seen within island groups themselves; in Orkney, the Island of Hoy is hillier and more rugged than surrounding islands and Harris is distinctive in being more mountainous than the islands of Lewis, North Uist, South Uist and Barra, in the Outer Hebrides.
Rivers
The ten major rivers of Scotland, in order of length, are:
- River Tay 193 km (120 miles)
- River Spey 172 km (107 miles)
- River Clyde 171 km (106 miles)
- River Tweed 156 km (97 miles)
- River Dee 137 km (85 miles)
- River Don 132 km (82 miles)
- River Forth 105 km (65 miles)
- River Findhorn 101 km (63 miles)
- River Deveron 98 km (61 miles)
- River Annan 79 km (49 miles)
Lochs
Freshwater bodies in Scotland are known as lochs, with the exception of the Lake of Menteith and one or two manmade "lakes".
- Loch Lomond 71.1 kmē (27.5 square miles), the largest freshwater body in Britain.
- Loch Ness 56.4 kmē (21.8 sq mi)
- Loch Awe 38.5 kmē (14.9 sq mi)
- Loch Maree 28.6 kmē (11.0 sq mi)
- Loch Morar 26.7 kmē (10.3 sq mi)
- Loch Tay 26.4 kmē (10.2 sq mi)
- Loch Shin 22.5 kmē (8.7 sq mi)
- Loch Shiel 19.6 kmē (7.6 sq mi)
- Loch Rannoch 19.1 kmē (7.4 sq mi)
- Loch Ericht 18.7 kmē (7.2 sq mi)
Distances to other countries
Scotland's only land border is with England, and runs for 96 kilometres (60 mi) between the basin of the River Tweed on the east coast and the Solway Firth in the west. The Atlantic Ocean borders the west coast and the North Sea is to the east. The island of Ireland lies only 30 kilometres (20 mi) from the southwestern peninsula of Kintyre; Norway is 305 kilometres (190 mi) to the east; the Faroes, 270 kilometres (168 mi) to the north; and Iceland, 740 kilometres (460 mi) to the northwest.
Human geography
According to the General Register Office for Scotland, the total population of Scotland stood at 5,116,900 in June 2006, an increase of 1.1% since the census of April 2001. Scotland accounts for just under 9% of the population of the United Kingdom, a figure which has been compounded by the gradual decline of Scotland's population since the early 1980s. However an increasing birth rate and higher levels of inward migration to Scotland have reversed the decline and contributed to the recent population growth.
Compared with the rest of Europe, Scotland has a low population density at 64 people per square kilometre, but is a highly urbanised country, with 82% of the population living in settlements of 3000 people or more. As a result, the majority of the population live in the Central Lowlands of Scotland, surrounding the chief cities of Glasgow and Edinburgh. Other concentrations of population include the northeast coast of Scotland - principally surrounding the city of Aberdeen and its environs - and around Inverness. With a population density of 8 people per square kilometre, the Highlands are the most sparsely populated part of the country. In these areas, the population is scattered in villages, small towns and isolated farmsteads or crofts.
Nearly 100 of Scotland's islands are inhabited, the most populous being Lewis with 16,782 people resident in 2001, primarily concentrated in Stornoway, the only burgh of the Outer Hebrides. Other island populations range down to only 1 on certain small isles. Between 1991 and 2001, the total number of people living on Scotland's islands fell by 3%. Bucking the trend, islands such as Tiree, Skye and Eigg all experienced increases in their respective populations, over the same period.
There are six cities in Scotland; Glasgow, Edinburgh, Aberdeen, Dundee, Inverness and Stirling. The 2001 census identified Glasgow as being the largest city in Scotland, with a total population of 629,501, while the Scottish capital, Edinburgh had a population of 448,624, in the same year. Between 1991 and 2001, the populations of Edinburgh and Stirling grew by 2.9% and 6.5% respectively. Conversely, Glasgow, Dundee and Aberdeen all experienced population decline over the same period. Aside from the cities, the most population growth occurred in West Lothian, East Lothian, Aberdeenshire and Perth and Kinross. The Western Isles saw a 9.8% fall in population between 1991 and 2001.
Political geography
The territorial extent of Scotland is generally that established by the 1237 Treaty of York between Scotland and England and the 1266 Treaty of Perth between Scotland and Norway. Exceptions include: the Isle of Man, which having been lost to England in the 14th century is now a crown dependency outside of the United Kingdom, the acquisition of Orkney and Shetland from Norway in 1472, and the permanent recovery of Berwick by England in 1482. Originally an independent country, Scotland joined with England to form the Kingdom of Great Britain in 1707 with the Acts of Union.
As one of the constituent parts of the United Kingdom, Scotland is represented by Members of Parliament at the Parliament of the United Kingdom at Westminster, London. In 1997 a referendum was held, and the people of Scotland voted for the establishment of a devolved Scottish Parliament in Edinburgh. The new parliament has the power to govern the country on Scotland-specific matters and has a limited power to vary income tax. The United Kingdom Parliament retains responsibility for Scotland's defence, international relations and certain other areas.
Between 1889 and 1975 Scotland was divided into burghs and counties, which were replaced by regions and districts. Since 1996, for the purposes of local government, Scotland has been divided into 32 council areas.
Rockall, a small and uninhabitable rocky islet in the North Atlantic, was annexed by the UK in 1955 and later declared part of Scotland by the Island of Rockall Act 1972. However, the legality of this claim is disputed by the Republic of Ireland, Denmark and Iceland and it is probably unenforceable in international law.
Economic Geography
The Gross domestic product (GDP) of Scotland is US$90 billion, giving a per capita GDP of US$18,000. Major industries include banking and financial services, steel, transport equipment, oil and gas, whisky, and tourism.
