Polar Wandering and Continental Drift

Alfred Wegener and continental drift

Darwin's continental drift

Lisbon is grandly celebrating the Darwin anniversaries, but to the east in Turkey things are different.

Brownian Motion with Polar Drift

Consider a strong Markov process X° that has continuous sample paths in Rd (d > 2) and the following two properties. (1) Away from the origin X° behaves like Brownian motion with a polar drift given in spherical polar coordinates by n{8)/2r. Here /i is a bounded Borel measurable function on the unit sphere in RJ, with average value Ji. (2) X° is absorbed at the origin. It is shown that X° reach...

From Continental Drift to Plate Tectonics

SINCE THE l6TH CENTURY, CARTOGRAPHERS HAVE NOTICED THE jigsaw-puzzle fit of the continental edges. Since the 19th century, geologists have known that some fossil plants and animals are extraordinarily similar across the globe, and some sequences of rock formations in distant continents are also strikingly alike. At the turn of the 20th century, Austrian geologist Eduard Suess proposed the theor...

Continental drift - Wikipedia, the free encyclopedia

Continental drift is the movement of the Earth's continents relative to each other. The hypothesis that continents 'drift' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However, it was not until the development of the theory of plate tectonics in the 1960s, that a sufficient geological explanation of that movement was understood. (This arti...
