WebThe normal thickness of continental crust is about 25 miles (40 km). During tectonic plate convergence, the continental crust is thickened to between 30 and 55 miles (48–89 km). Crustal thickening results from a number of processes that include folding, thrust faulting, metamorphism, intrusion, and tectonic accretion. filipino talk show hostsWebThe crust is the outer layer of the Earth.
