Iceland (/ˈaɪslənd/; Icelandic: Ísland [ˈistlant]) is a Nordic island country between the North Atlantic and the Arctic Ocean. It has a population of 329,100 and an area of 103,000 km² (40,000 sq mi), making it the most sparsely populated country in Europe. The capital and largest city is Reykjavík. Reykjavik and the surrounding areas in the southwest of the country are home to over two-thirds of the population. Iceland is volcanically and geologically active. The interior consists of a plateau characterised by sand and lava fields, mountains and glaciers, while many glacial rivers flow to the sea through the lowlands.
