WE really are one world, according to the findings of AlfredWegener, a guy who really knew his weather. Born on Nov. 1, 1880, in Germany, he received a Ph.D. in astronomy from the University of Berlin ...

In 1963, Fred Vine, Drummond Matthews, and others found that the crust surrounding the midocean ridges showed alternating bands -- each band magnetized with a polarity opposite the surrounding bands.

Photo: Harry Hess argues that the continents had once been one, and have drifted apart. With the discovery of plate tectonics and the mapping of the earth into about 12 plates, plus the understanding ...

Graphic showing the Mid-Atlantic Ocean Ridge (red line) and how melting ice from Greenland caused changes in the motion of Earth's crust (purple arrows). Around 10,000 years ago as the last Ice Age ...

The Origin of the Oceanic Ridges Current models of sea-floor spreading and continental drift imply convection in the earth's mantle as the driving mechanism. Critical analysis of this assumption leads ...
