The Lowland Zone

In general the lowland zone is a great plain with a gentle, undulating surface and extensive areas of almost-level ground. It receives less rain and more sunshine than the highland zone and much of the soil in the zone is fertile. Most of the lowland region is less than 150 m (500 ft) above sea level, and the hills rarely reach more than 300 m (1,000 ft) above sea level. It has been extensively inhabited, farmed, and grazed for thousands of years. Most of Britain’s population lives densely packed into the lowland zone, which covers most of England. The metropolis of London and most of Britain’s large cities are located in the lowland zone.

The flattest lands in the lowland zone are in the east, particularly on the large, hump-shaped area called East Anglia. The inlet called the Wash is located off East Anglia’s northern coast. The Wash was once surrounded by the flat, swampy areas of the Fenlands, or the Fens, most of which has now been drained. The broad, rolling Midland Plain is south of the Pennine Chain. Northwest of this plain, on the western side of the Pennines, is the Lancashire-Cheshire plain. Another plain extends from the eastern slope of the Pennines to the sea. It is broken in the north by the Yorkshire Moors, a high wasteland overgrown with coarse plants.

Several chains of low hills break up the lowland plain. They are sometimes called scarplands or escarpments, meaning that they tend to drop steeply on one side and slope gently downward on the other side. One of these upland ridges, the South Downs, runs along the southern coast eastward from the Salisbury Plain. Running parallel to this ridge, south of the Thames valley, are the North Downs. In between the North Downs and the South Downs is a region called The Weald, an area of scenic, gentle hills. Another elevated chain is the Chiltern Hills, which stretch southwest from the central part of the lowland plain. The Cotswold Hills lie to the west near Wales. The Cotswolds and the plain’s northern hills have a limestone base, while the Downs have a chalk base.

Rivers and Lakes

Since Britain has a moist climate with much rainfall, rivers and lakes are numerous. Rivers in central and eastern Britain tend to flow slowly and steadily all year long because they are fed by the frequent rain. Many have been navigable, and from the earliest times they have served peoples interested in either commerce or invasion. The Highlands act as a divide and determine whether rivers flow west to the Irish Sea or east to the North Sea. Rivers and streams moving westward down from the Highlands tend to be swift and turbulent; rivers flowing eastward tend to be long, graceful, and gentle, with slowly moving waters.

The Thames and the Severn are the longest rivers in Britain and are almost equal in length. The Severn flows south out of the mountains of central Wales to the Bristol Channel at Bristol. It is 354 km (220 mi) long. The Thames, 338 km (210 mi) long, flows eastward out of the Cotswold Hills and weaves through the metropolis of London. The Thames provides water to the city of London and is used to carry commercial freight. Other important rivers in England are the Mersey, which enters the Irish Sea at Liverpool; the River Humber on the east coast, into which the Trent River and several other rivers flow; and the Tyne River in northern England, which flows past Newcastle upon Tyne to the North Sea.

In Scotland the important rivers are the Clyde and the Forth, which are joined by a canal. The River Clyde flows northwest, past Glasgow, and empties into the Atlantic at the Firth of Clyde. (Firth is the Scottish name for an arm of the sea that serves as the broad estuary of a river.) The River Forth flows eastward into the Firth of Forth, where Edinburgh rises on its south bank. The most important rivers in Northern Ireland are the Lagan, the Bann, and the Foyle.

Most of the large lakes in the United Kingdom are located in the upland areas of Scotland and northern England, although Lough Neagh in Northern Ireland is the largest lake in the United Kingdom. Loch Lomond, on the southwestern edge of the Highlands of Scotland, is the largest on the island of Great Britain, measuring 37 km (23 mi) long and from 1.6 to 8 km (1 to 5 mi) wide. Lake Windermere is the largest of the 15 major lakes in the famous Lake District of northwestern England. It is about 1.6 km (1 mi) wide and more than 16 km (10 mi) long.

Coastline

Great Britain’s coastline is highly irregular, with many bays and inlets that provide harbors and shelters for ships and boats. Coastal trade involving ships sailing along the coast has been carried on since ancient times. The coastline is about 8,000 km (about 5,000 mi) long and affords some of the best scenery in Britain. The western coast is characterized by cliffs and rocky headlands, especially where the Highlands meet the sea in northwestern Scotland. On the more gentle southern and eastern coasts there are many sand or pebble beaches as well as tall limestone or chalk cliffs, the most famous of which are the White Cliffs of Dover in the southeast.

A few islands lie just off of Britain’s coast. The Hebrides, an archipelago of about 500 islands, cover a considerable area along the coast of western Scotland; the isle of Anglesey lies just off the coast of northwestern Wales; and the Isle of Wight is off England’s southern coast. Northern Ireland has a beautiful and rugged coastline and is the location of the famous and unique Giant’s Causeway, an expansive and curious formation of rocks shaped like giant cylinders.

Soils

Britain’s soil quality varies greatly. In northern areas the soils are thin, lying right above rock formations, while the south possesses areas of rich loam and heavy clay soils. When handled carefully the soils of eastern and south central England are very productive. While about three-fourths of the land in Britain is suitable for agriculture, only 24 percent of this land is used to grow crops. Almost all of the rest is planted with grass or used as grazing land.

Forests and Woodlands

Trees grow well and quickly in the heavy soils of England, and for a long time prehistoric settlers did not have tools strong enough to cut down the heavy oak forests. Over the centuries the expanding human population cut back the forests, so that today only 11.8 percent of the United Kingdom is forested, roughly 3 million hectares (7 million acres). Only 7 percent of England is covered by forest, 15 percent of Scotland, 12 percent of Wales, and 5 percent of Northern Ireland. Efforts have been made in Britain to grow more trees and expand the managed forest areas. Local authorities have the power to protect trees and woodlands. It is an offense to cut down trees without permission, and when trees protected by the government die they must be replaced.
