How does continental drift happen
WebOct 1, 2024 · The theory of plate tectonics argues that Earth's outer layer—the crust—is composed of large platelike sections of solid rock. These plates essentially float on weaker layers of partially melted rock in the mantle below. Scientists believe that convection circulation … WebIn 1915, Wegener proposed his continental drift theory. He said that the continents floated atop the mantle-a heavier, denser layer of rocks deep within the earth. Wegener predicted …

WebThis fit of Africa and South America becomes even better if we define the edges of continents by their continental shelves. The continental shelf is defined as the area of seabed around a large landmass where the sea is relatively shallow compared with the open ocean. The continental shelf is geologically part of the continental crust. WebFeb 23, 2004 · The continental shift led to changes in ocean circulation and Earth's climate. The collision of the Indian and Eurasian Plates uplifted the Himalayas and the Tibetan Plateau, which scientists believe resulted in …
WebConverging currents drive plates into each other. Diverging currents pull them apart. This is mostly true. Hot mantle rock rises from the core and moves along under the crust until it grows cool and heavy and sinks back down again. But the plates aren't just passively riding these currents around like a bunch of suitcases at the baggage claim.

The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1… earth read aloudWebTwo plates carrying continental crust collide when the oceanic lithosphere between them has been eliminated.
