Physicists in the US have performed a simple table-top experiment that could provide new insight into why the Earth’s continents drift apart and then move back together over several hundred-million ...

Palaeomagnetic comparisons between Europe and North America / S.K. Runcorn -- Geological evidence bearing upon continental drift / T.S. Westoll -- Palaeomagnetic data from the Gondwanic continents / K ...

Colliding continents The movement of Earth's major continental tectonic plates is speeding up, suggests a new study. The study, presented at the Goldschmidt Geochemistry Conference in Sacramento ...

Drifting of the large tectonic plates and the superimposed continents is not only powered by the heat-driven convection processes in the Earth's mantle, but rather retroacts on this internal driving ...

IT has become clear in recent years that there is a formidable case for continental drift. The most convincing single piece of evidence comes from palæomagnetism 1, but this is amply supported by a ...

The possible causes of convection in the Earth's mantle are examined, and it is concluded that radiogenic heating together with thermal conduction is most likely to provide the driving force for any ...

Melting glaciers in North America 10,000 years ago may have given continental drift a bit of a push. Similar activity in Greenland now could eventually trigger volcanic eruptions in Iceland.

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 to an alternative explanation ...
