  2. List of tectonic plate interactions - Wikipedia

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

    Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. 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 ...

  3. Convergent boundary - Wikipedia

    en.wikipedia.org/wiki/Convergent_boundary

    A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction .

  4. List of tectonic plates - Wikipedia

    en.wikipedia.org/wiki/List_of_tectonic_plates

    Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)

  5. 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 the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.

  6. Oceanic trench - Wikipedia

    en.wikipedia.org/wiki/Oceanic_trench

    Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate .

  7. Accretionary wedge - Wikipedia

    en.wikipedia.org/wiki/Accretionary_wedge

    An accretionary wedge or accretionary prism forms from sediments accreted onto the non-subducting tectonic plate at a convergent plate boundary. Most of the material in the accretionary wedge consists of marine sediments scraped off from the downgoing slab of oceanic crust , but in some cases the wedge includes the erosional products of ...

  8. Obduction - Wikipedia

    en.wikipedia.org/wiki/Obduction

    Obduction is a geological process whereby denser oceanic crust (and even upper mantle) is scraped off a descending ocean plate at a convergent plate boundary and thrust on top of an adjacent plate. [1] [2] When oceanic and continental plates converge, normally the denser oceanic crust sinks under the continental crust in the process of ...

  9. Interplate earthquake - Wikipedia

    en.wikipedia.org/wiki/Interplate_earthquake

    There are three types of plate boundaries to consider in the context of interplate earthquake events: [4] Transform fault: Where two boundaries slide laterally relative to each other. Divergent boundary: Where two boundaries move apart. Convergent boundary: Where one plate moves towards, and potentially subducts beneath, another plate.
