  2. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    The relative movement of the plates typically ranges from zero to 10 cm annually. [5] Faults tend to be geologically active, experiencing earthquakes, volcanic activity, mountain-building, and oceanic trench formation. Tectonic plates are composed of the oceanic lithosphere and the thicker continental lithosphere, each topped by its own kind of ...

  3. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Tectonics

    Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental end of ...

    Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]

  5. Continental drift - Wikipedia

    en.wikipedia.org/wiki/Continental_drift

    Continental drift is the theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere.

    Geologists modeled the last billion years of Earth's tectonic plate evolution in unprecedented detail, then animated it in a mesmerizing video.

  7. Mountain formation - Wikipedia

    en.wikipedia.org/wiki/Mountain_formation

    Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.

    Take yourself back to fifth-grade science for a second. You might have learned that earthquakes are caused by the sudden movement of big, underground sheets of rock, called tectonic plates.

  9. Expanding Earth - Wikipedia

    en.wikipedia.org/wiki/Expanding_Earth

    The motions of tectonic plates and subduction zones measured by a large range of geological, geodetic and geophysical techniques helps verify plate tectonics. [29] [4] [30] Imaging of lithosphere fragments within the mantle is evidence for lithosphere consumption by subduction. [4] [30]
