Epeirogenic movement can be permanent or transient. Transient uplift can occur over a thermal anomaly due to convecting anomalously hot mantle , and disappears when convection wanes. Permanent uplift can occur when igneous material is injected into the crust , and circular or elliptical structural uplift (that is, without folding) over a large ...
Epeirogenic uplift is a long-wavelength form of uplift and be split up into two separate categories, which is transient and permanent. Permanent epeirogenic uplift is possibly mainly produced by magmatic underplating, [ 10 ] while transient uplift is more involved with mantle convection . [ 9 ]
Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges.
[4] [a] An inland sea is only an epeiric sea when a continental interior is flooded by marine transgression due to sea level rise or epeirogenic movement. [6] [9] An epicontinental sea is synonymous with an epeiric sea. [9] The term "epicontinental sea" may also refer to the waters above a continental shelf. This is a legal, not geological ...
Dynamic rejuvenation may be caused by the epeirogenic uplift of a land mass. Warping or faulting of a drainage basin will steepen the stream gradient followed by the downcutting. The effect of seaward tilting can be felt immediately only when the direction of that stream is parallel to the direction of tilting.

Isostasy (Greek ísos 'equal', stásis 'standstill') or isostatic equilibrium is the state of gravitational equilibrium between Earth's crust (or lithosphere) and mantle such that the crust "floats" at an elevation that depends on its thickness and density.
