Mechanizmy of Tectonic Uploft

Transform boundaries, chacterized by plates sliding patt each tequirontally, typically do not produce large-scale vertical upfilt.

Te mosty spectular outcome of tectonic uplift is orogeny - thee formation of mountain ranges through gh crustal deformation. Mountain belts are dynamic, evolving systems that grow, erode, and respond to ongoing tectonic forces. Orogenic processes involve folding, faulting, metamorfism, and magmatism, all contriing to crustal squening and elevation gain.
