Which is a true statement?
A) A disconformity in the Grand Canyon can be observed when the sedimentary layers below the unconformity are tilted due to tectonic activity and are overlain by flat, sedimentary rocks that are younger
B) An angular unconformity in the Grand Canyon can be observed when the sedimentary layers below the unconformity are tilted due to tectonic activity and are overlain by flat, sedimentary rocks that are younger
C) A nonconformity in the Grand Canyon can be observed when the sedimentary layers below the unconformity are tilted due to tectonic activity and are overlain by flat, sedimentary rocks that are younger
D) A geo-conformity in the Grand Canyon can be observed when the sedimentary layers below the unconformity are tilted due to tectonic activity and are overlain by flat, sedimentary rocks that are younger

Question

Quizplus · Accepted Answer

An angular unconformity is characterized by an underlying set of tilted or folded sedimentary rocks that are overlain by younger, more flat-lying strata. This description matches the scenario given in option B, indicating an angular unconformity.
