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.

The morphism h is a lift of f (commutative diagram). In category theory, a branch of mathematics, given a morphism f: X → Y and a morphism g: Z → Y, a lift or lifting of f to Z is a morphism h: X → Z such that f = g ∘ h.
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 ...
River erosion can be driven by tectonic uplift, climate, or potentially both mechanisms. It is difficult in many areas, however, to decisively pinpoint whether tectonism or climate change can individually drive tectonic uplift, enhanced erosion, and therefore terrace formation. In many cases, simplifying the geologic issue to tectonic-driven vs ...
These forms result from accelerated entrenchment caused by recent tectonic activity such as especially vertical uplift. The uplift creates high-standing plateaus and as a result, perpetuates the downward erosive power of existing rivers.
[23] [24] Different elevated passive continental margins most likely share the same mechanism of uplift. This mechanism is possibly related to far-field stresses in Earth's lithosphere . According to this view elevated passive margins can be likened to giant anticlinal lithospheric folds, where folding is caused by horizontal compression acting ...
That support can come in different forms, including: Talking with a mental health provider. Joining a support group. Opening up to a loved one about your struggle. Connecting with an online community.
Formation of a metamorphic core complex. Metamorphic core complexes are exposed areas of deep crust brought to the surface by crustal extension (stretching). [1] They form, and are exhumed, through relatively fast [citation needed] transport of middle and lower continental crust to the Earth's surface [2] in the form of uplifting welts of hot rock and magma.
