Answer:
nonconformity
Explanation:
There are multiple types of unconformity that occur in nature, all of which are base on the relative position of the types of rocks. The nonconformity is one of the unconformities. This type of unconformity occurs when sedimentary rock overlies igneous or metamorphic rocks that existed there before the sedimentary rocks covered them. The nonconformity can be seen in lots of places around the world, but it is most common on places where there are water bodies like lakes, seas, oceans, ponds, marshes, or on places where there were water bodies of this type in the past.
