用英语介绍一下北海的概况如题 200到300字之间
The North Sea is a marginal,epeiric sea on the European continental shelf.The Dover Strait and the English Channel in the south and the Norwegian Sea in the north connect it to the Atlantic Ocean.It is more than 970 kilometres (600 mi) long and 580 kilometres (360 mi) wide,with an area of around 750,000 square kilometres (290,000 sq mi).A large part of the European drainage basin empties into the North Sea including water from the Baltic Sea.Much of the sea's coastal features are the result of glacial movements.Deep fjords and sheer cliffs mark the Norwegian and parts of the Scottish coastline,whereas the southern coasts consist of sandy beaches and mudflats.These flatter areas are particularly susceptible to flooding,especially as a result of storm tides.Elaborate systems of dikes have been constructed to protect coastal areas.The Romans and the Vikings extended their territory across the sea.The Hanseatic League,the Netherlands,and finally the British sought to dominate commerce on the North Sea and through it to access the markets and resources of the world.Commercial enterprises,growing populations and limited resources gave the nations on the North Sea the desire to control or access it for their own commercial,military,and colonial ends.In recent decades,its importance has shifted from the military and geopolitical to the purely economic.While traditional activities such as fishing and shipping have continued to grow,newer resources such as fossil fuels and wind and wave energy have also been discovered or developed.
