Quizplus · Accepted Answer

Conglomerate is the youngest geologic unit visible in the cross section. This is because it is on top of the other rock layers and has not been subjected to any folding or faulting that would have caused it to be uplifted and exposed to the surface. Granite, limestone, and marble are all older rock units that are lower in the cross section.
