Earth Science Question

Question

This question is an Earth Science question.

What happens when you see an nonconformity in a strati graphic column?

There is always erosion, There is time missing in the section you are looking at, It means nothing has changed since the rock layers have been there, or It is only evident in metamorphic rocks.

Answer 1

Hi Lisa, Nonconformities form when there are sedimentary rocks deposited over an igneous or metamorphic rock. They typically indicate that a long period of erosion (missing time) has occurred prior to the deposition of the sedimentary cover.
