  2. Delamination (geology) - Wikipedia

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

    The lithosphere layer is composed of two parts, an upper, the crustal lithosphere and lower, the mantle lithosphere. The crustal lithosphere is in unstable mechanical equilibrium because the underlying mantle lithosphere has a greater density than the asthenosphere below. [ 1 ]

  3. Lithospheric flexure - Wikipedia

    en.wikipedia.org/wiki/Lithospheric_flexure

    Cartoon showing the isostatic vertical motions of the lithosphere (grey) in response to a vertical load (in green) In geology, lithospheric flexure (also called regional isostasy) is the process by which the lithosphere (rigid, thin outer layer of the Earth) bends under the action of forces such as the weight of a growing orogeny or changes in ice thickness related to glaciation.

  4. List of tectonic plates - Wikipedia

    en.wikipedia.org/wiki/List_of_tectonic_plates

    Lithosphere – Outermost shell of a terrestrial-type planet or natural satellite; Ocean – Body of salt water covering most of Earth; Plate tectonics – Movement of Earth's lithosphere List of tectonic plate interactions – Types of plate boundaries; Supercontinent – Landmass comprising more than one continental core, or craton

  5. Lithosphere–asthenosphere boundary - Wikipedia

    en.wikipedia.org/wiki/Lithosphere–asthenosphere...

    A diagram of the internal structure of Earth. The lithosphere consists of the crust and upper solid mantle (lithospheric mantle). The green dashed line marks the LAB. The lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure.

  6. Lithosphere - Wikipedia

    en.wikipedia.org/wiki/Lithosphere

    The tectonic plates of the lithosphere on Earth Earth cutaway from center to surface, the lithosphere comprising the crust and lithospheric mantle (detail not to scale). A lithosphere (from Ancient Greek λίθος (líthos) 'rocky' and σφαίρα (sphaíra) 'sphere') is the rigid, [1] outermost rocky shell of a terrestrial planet or natural satellite.

  7. Earth's crust - Wikipedia

    en.wikipedia.org/wiki/Earth's_crust

    Plates in the crust of Earth. Earth's crust is its thick outer shell of rock, referring to less than one percent of the planet's radius and volume.It is the top component of the lithosphere, a solidified division of Earth's layers that includes the crust and the upper part of the mantle. [1]

  8. Subcontinental lithospheric mantle - Wikipedia

    en.wikipedia.org/wiki/Subcontinental...

    The boundary between these two layers is rheologically based and is not necessarily a strict function of depth. Specifically, oceanic lithosphere (lithosphere underneath the oceanic plates) and subcontinental lithosphere, is defined as a mechanical boundary layer that heats via conduction and the asthenosphere is a convecting adiabatic layer.

  9. 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 ...
