Which mechanism causes crustal thickening when compressive forces occur at continental convergent plate boundaries?

💡 Explanation

When continents collide, thrust faulting occurs because the crust shortens via brittle deformation, stacking rock layers. Therefore thrust faulting and crustal shortening causes crustal thickening, rather than isostatic rebound, magmatic underplating or lithospheric delamination, which involve alternative processes.
