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.
In geology, the elastic-rebound theory is an explanation for how energy is released during an earthquake. As the Earth's crust deforms, the rocks which span the opposing sides of a fault are subjected to shear stress. Slowly they deform, until their internal rigidity is exceeded.

Tectonic plate boundaries, showing the directions of plate movements. Different kinds of boundaries. The different ways in which tectonic plates rub against each other under the ocean or sea floor to create submarine earthquakes. The type of friction created may be due to the characteristic of the geologic fault or the plate boundary as follows.
Each boundary type is associated with different geological marine features. Divergent plates are the cause for mid-ocean ridge systems while convergent plates are responsible for subduction zones and the creation of deep ocean trenches. Transform boundaries cause earthquakes, displacement of rock, and crustal deformation. [8] [27] [26] [28]
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 ...
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.
Subsidence at a divergent plate boundary is a form of vertical displacement which occurs when a plate begins to split apart. [2] As intrusive magma widens the rift zone of a divergent plate boundary the layers of crust on the surface above the rift will subside into the rift, creating a vertical displacement of those layers of surface crust.
