can you tell me the history of the North Sea? 
 Yes. The North Sea is part of the Atlantic Ocean. There are many areas that actually have access to the North Sea and rivers that empty into it. 
 oh wow, what else can you tell me about the history? 
 Naturally, it has a long history, and has had a part as a fishery and has been integral to European shipping lanes. 
 Ok can you tell me anything about tourism? 
 Sure. The coasts, particularly the German, Dutch, Danish and Beligan, have been developed for tourism. 
 Can you tell me anything about the Geography of the North Sea? 
 The North Sea primarily lies on the European continental shelf and has a depth of 90 miles. 
 Can you give me any more information on geography? 
 Sure! Additionally, the coastline as it's known today formed after the last Glacial Maximum. At that time, it began to flood the European continental shelf. 
 Thank you so much for all your help. Have a great day! 
 You're welcome!
