Tectonic uplift
Tectonic uplift is the rise of Earth’s crust caused by forces associated with plate motion, including faulting, folding, and crustal thickening.
Isostasy: The gravitational balance between Earth’s crust and the denser mantle beneath it. Crust rises or sinks as its mass changes and the lithosphere seeks buoyant balance.
Orogeny: The set of tectonic processes that builds a mountain belt, often through collision, compression, and crustal deformation. Mountain-building episodes commonly combine uplift with folding, faulting, and crustal thickening.
Himalayas: A mountain range in Asia formed by convergence between the Indian and Eurasian plates. Ongoing collision thickens crust and raises parts of the range and Tibetan Plateau.
Epeirogenic movement: Broad, generally gentle vertical movement of large regions of continental crust. It describes regional vertical motion, whereas tectonic uplift can emphasize specific structures and mechanisms.
Crustal thickening: An increase in the thickness of Earth’s crust, commonly caused by compression and tectonic convergence. Converging plates can stack and deform crust, raising high plateaus and mountain belts.
Mountain building: The tectonic processes that create and reshape mountain ranges. Tectonic uplift is one component of the broader construction of mountain landscapes.
Tibetan Plateau: A vast, high-elevation region of Central Asia with exceptionally thick continental crust. Its elevation reflects extensive crustal thickening and other processes linked to continental collision.
Isostatic rebound: The rise of crust after removal of a load, such as melting ice or eroded rock. Rebound is driven by unloading and buoyant adjustment, not necessarily by active tectonic deformation.
Thrust fault: A low-angle reverse fault along which one block of crust moves over another. Repeated thrusting shortens and thickens crust, producing uplift in fold-and-thrust belts.
Exhumation: The movement of rocks toward Earth’s surface from deeper crustal levels. Uplift can bring buried rocks upward, though erosion must remove overlying material for exposure.
