  2. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.

  3. Slab (geology) - Wikipedia

    en.wikipedia.org/wiki/Slab_(geology)

    [11] [12] Marianas Trench is an example of a deep slab, thereby creating the deepest trench in the world established by a steep slab angle. [13] Slab breakoff occurs during a collision between oceanic and continental lithosphere, [ 14 ] allowing for a slab tear; an example of slab breakoff occurs within the Himalayan subduction zone.

  4. 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 ...

  5. Slab pull - Wikipedia

    en.wikipedia.org/wiki/Slab_pull

    Slab pull is a geophysical mechanism whereby the cooling and subsequent densifying of a subducting tectonic plate produces a downward force along the rest of the plate. In 1975 Forsyth and Uyeda used the inverse theory method to show that, of the many forces likely to be driving plate motion, slab pull was the strongest. [1]

  6. Slab suction - Wikipedia

    en.wikipedia.org/wiki/Slab_suction

    This driving force is important when the slabs (or portions thereof) are not strongly attached to the rest of their respective tectonic plate. They cause both the subducting and overriding plate to move in the direction of the subduction zone. [1] This force occurs between two colliding plates where one is subducting beneath the other.

  7. Tectonic uplift - Wikipedia

    en.wikipedia.org/wiki/Tectonic_uplift

    Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...

  8. Tectonophysics - Wikipedia

    en.wikipedia.org/wiki/Tectonophysics

    Tectonophysics is concerned with movements in the Earth's crust and deformations over scales from meters to thousands of kilometers. [2] These govern processes on local and regional scales and at structural boundaries, such as the destruction of continental crust (e.g. gravitational instability) and oceanic crust (e.g. subduction), convection in the Earth's mantle (availability of melts), the ...

  9. List of tectonic plate interactions - Wikipedia

    en.wikipedia.org/wiki/List_of_tectonic_plate...

    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]
