Meanwhile, let us take a fresh look at the Atlantic Ocean to see if the theory of continental drift might still leave room for a missing continent there. When a computer was used to reassemble the continental jigsaw, the fit across the Atlantic was found, with some adjustment, to be fairly satisfactory. But that picture does not take account of a fascinating underwater feature known as the mid-Atlantic Ridge. This mountainous ridge, nearly two miles high and hundreds of miles wide, runs in an S-curve down the Atlantic midway between the Americas and Africa and Europe, following the contours of those continents and marking its course above water with a number of islands, such as the Azores, Ascension Island, and Tristan da Cunha.
