  • Wegener's idea of continental drift stemmed from an intuitive impression of the coincidence of both sides of the Atlantic Ocean. This coincidence is represented by the fit of coastlines of South America and Africa on both sides of the Atlantic. In recent decades, however, the submarine geophysical and geological investigations have discovered that the magnetic anomalies, seismic tomographic images and seismic profiles of the Atlantic Ocean and the continents on its both sides, and the zircon ages of the determined rocks in mid-ocean ridge indicate the formation of the ocean by continental rifting. There is no significant horizontal displacement of the continents on both sides. Furthermore, the existence of continental roots as deep as 300-400 km in the world's continents seem to have basically denied the possibility of large-scale continental drift.
