Gap in a rock layers that develop when agents of erosion remove existing Rock layers is

Answer: unconformity

Explanation:

An unconformity is a gap in a rock record that has been caused by weathering or erosion. The name refers to the way they don't adhere to usual geological expectations.

An exemplary sequence of rocks would have all the strata stack up. If they don't, the gap between the mismatched strata is an unconformity.

The different kinds of unconformity are angular conformity, disconformity, and nonconformity.

Gaps in rock layers that develop when agents of erosion remove existing rock layers are called unconformities.
