Question

Quizplus · Accepted Answer

A shield is a type of continental crust that lacks sedimentary cover and is composed mainly of Precambrian crystalline rocks. It is typically a broad, flat region that has undergone millions of years of erosion and tectonic activity. Platforms, rift zones, and plateaus may also contain Precambrian rocks, but they often have some type of sedimentary or volcanic cover material, and may have different geological histories or formations.
