Answer:

An unconformity is a feature which causes a 'gap in the geologic record'.

Explanation:

• Unconformities are features that don't conform to typical or normal geographic expectations and are gaps between old eroded sedimentary, metamorphic or igneous rocks.
• An unconformity separates rock masses of different ages due to in continuous sedimentation, buried erosions or "non-depositional surface".
• 'Various types of unconformities' are there like angular, disconformity, paraconfirmity, angular unconformity, nonconformity (non-layering of rocks) etc.
• "Different types of unconformities" can be found in Grand Canyon in the USA.
