The North Sea is a marginal sea of the Atlantic Ocean located between the United Kingdom (particularly England and Scotland), Denmark, Norway, Sweden, Germany, the Netherlands, Belgium and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 kilometres (600mi) long and 580 kilometres (360mi) wide, with an area of around 570,000 square kilometres (220,000sqmi).
Southeast Asia
Southeast Asia covers about 4.5 million km2 (1.7 million mi2), which is 10.5% of Asia or 3% of earth's total land area. Its total population is more than 655 million, about 8.5% of the world's population. It is the third most populous geographical region in the world after South Asia and East Asia.[8] The region is culturally and ethnically diverse, with hundreds of languages spoken by different ethnic groups.[9] Ten countries in the region are members of ASEAN, a regional organisation established for economic, political, military, educational and cultural integration amongst its members.[10]
