Well, obviously now, you can’t walk from New York to London (or at least, without even getting wet by the wide North Atlantic Ocean.) But do you know that about 225 million years ago, the United Kingdom was part of North America?
The North Atlantic breakup is a geological event that happened over millions of years, during which the supercontinent Pangea broke up. As modern-day Europe (the Eurasian plate) and North America (North American Plate) separated during the final breakup of Pangea in the early Cenozoic Era, they formed the North Atlantic Ocean.
The North Atlantic geographic area comprises the North Atlantic ocean, Iceland, Greenland, the United Kingdom, Denmark and Norway.
