The megaflood made Britain what it is today, geographically
Britain became separated from mainland Europe after a catastrophic flood some time before 200,000 years ago, a sonar study of the English Channel confirms.

Scientists tell the journal Nature that the torrent probably came from a giant lake in what is now the North Sea.
