The United Kingdom is made up of islands in the Atlantic Ocean. The specific bodies of water that surround it are the North Sea, the English Channel, and the Celtic Sea. When taken together, the UK has the 12th-longest coastline in the entire world. The total area of the UK is around 242,500 square kilometers (93,600 square miles) and is populated by approximately 66 million people.
The United Kingdom or the UK for short is an independent country comprised of multiple nations. These nation-states are England, Scotland, Wales and Northern Ireland. For our purposes here, we will talk about the entire region as the UK, even in reference to countries and territories that are not technically part of it such as Ireland and some other surrounding islands.
This region is part of Europe and sits to the northwest of the mainland part of the continent. It is a region with a lot of important history, economic and political power and, as an island nation, a lot of great diving locations.
