  England accounts for 53 per cent of the UK, covering 50,350 square miles (130,395 km 2). Most of the country consists of lowland terrain, with upland and mountainous terrain northwest of the Tees–Exe line which roughly divides the UK into lowland and upland areas. Lowland areas include Cornwall, the New Forest, the South Downs and the Norfolk Broads. Upland areas include the Lake District, the Pennines, the Yorkshire Dales, Exmoor and Dartmoor. The main rivers and estuaries are the Thames, Severn, and the Humber. England's highest mountain is Scafell Pike, at 978 metres (3,209 ft) in the Lake District; its largest island is the Isle of Wight.
  
  Scotland accounts for 32 per cent of the UK, covering 30,410 square miles (78,772 km 2). This includes nearly 800 islands, notably the Hebrides, Orkney Islands and Shetland Islands. Scotland is the most mountainous constituent country of the UK. The Highlands to the north and west are the more rugged region containing the majority of Scotland's mountainous land, including the Cairngorms, Loch Lomond and The Trossachs and Ben Nevis which at 1,345 metres (4,413 ft) is the highest point in the British Isles.
  
  Wales accounts for less than 9 per cent of the UK, covering 8,020 square miles (20,779 km 2). It is mostly mountainous, though South Wales is less mountainous than North and mid Wales. The highest mountains in Wales are in Snowdonia and include Snowdon (Welsh: Yr Wyddfa) which, at 1,085 metres (3,560 ft), is the highest peak in Wales. Wales has over 1,680 miles (2,704 kilometres) of coastline including the Pembrokeshire Coast. Several islands lie off the Welsh mainland, the largest of which is Anglesey (Ynys Môn).
  
  Northern Ireland, separated from Great Britain by the Irish Sea and North Channel, has an area of 5,470 square miles (14,160 km 2) and is mostly hilly. It includes Lough Neagh which, at 150 square miles (388 km 2), is the largest lake in the British Isles by area, Lough Erne, which has over 150 islands, and the Giant's Causeway, which is listed by UNESCO as a World Heritage Site. The highest peak in Northern Ireland is Slieve Donard in the Mourne Mountains at 852 metres (2,795 ft).
