In mesa-and-scarp topography, ________ are typically the most resistant layers which form a caprock.

Question

Quizplus · Accepted Answer

Limestone and sandstone are typically harder and more resistant to erosion, which allows them to form the caprock on top of mesas and scarps. Granite and basalt are also resistant, but are not typically found in layered formations. Shale and volcanic ash are not usually resistant enough to form caprocks. Gneiss and loess are not common types of rock found in mesa-and-scarp topography. Folds and faults are not layers of rock, but rather structural features.
