Plate tectonics is the theory used to explain the structure of the Earth’s crust and many of the associated phenomena. The rigid lithosphere is split into 7 major ‘plates’ that slowly move on top of ...

The breakup of the South Atlantic region, which led to the separation of the African and South American continents, is a well-known global phenomenon. In fact, the famous continental drift theory put ...

Continental Drift Theory - When Continents Were Supposed to Stand Still When meteorologist Alfred Wegener proposed in 1912 ...

Were all continents once snuggled together in a mammoth land mass surrounded by a single shimmering sea? Did the continents begin to drift apart some 200 million years ago? Some scientists believe so, ...

While the Google Doodle illustrates the Theatrum Orbis Terrarum — with notes that reflect Ortelius’s compendium of data, names of scientists, theories, and even sea monsters — a closer look at the ...

Geoscientists have solved an age-old mystery of oceanic volcanism and plate tectonics, explaining why some islands contain so ...

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 ...

THE complex problem of continental drift has everywhere been the subject of animated discussion in geological circles during recent years, and the publication of the papers presented at a symposium ...

STUDENTS of fossils are interested in Wegener's theory that the continents are floating on a heavier layer of the earth's crust which, sometimes at least, becomes plastic and allows them to move ...
