Question

Quizplus · Accepted Answer

A platform is a portion of the craton that is covered by a thin layer of sedimentary rocks, typically less than 3,000 feet thick. These sedimentary rocks were deposited on top of an ancient igneous or metamorphic basement rock, and have been relatively undisturbed since their deposition. Shields, continental shelves, and plateaus are not characterized by a thin layer of sedimentary rocks covering an underlying basement rock.
