It is usually due to erosion of lack of deposition.

Unconformity
The trilobite species Eldredgeops rana is a common New York State index fossil found in Devonian rock layers. If a rock layer containing this index fossil is missing due to unconformity, it suggests a gap in the rock record where deposition ceased, erosion occurred, and then new sediment layers were deposited on top.
An unconformity. It is a boundary in the rock record where a part of the geologic column is missing due to erosion, non-deposition, or a combination of both.
An unconformity is created when there is a gap in the rock record due to erosion or non-deposition of sediment. When sedimentation stops and then restarts, there is a period of time where the underlying rock is exposed to erosion, creating a gap in the sequence of rock layers. This gap represents missing geological time in the rock record.
Type your answer an unconformity indicates where a layer is missing in the strata sequence, so it tells you that there is a missing rock layerhere...
Unconformity. An unconformity represents a gap in the geologic record where erosion or non-deposition has led to a break in the sequence of rock layers.
Unconformity
unconformity
This is called an unconformity, which represents a gap in the geological record where layers have been eroded away or were never deposited. Unconformities can help geologists understand the history of rock formations and the processes that have shaped the Earth's surface.

A disconformity is a type of unconformity characterized by erosion or non-deposition of layers of rock, resulting in parallel layers above and below the unconformity. It represents a period of missing geological time in the rock record.
An unconformity is a gap in the sequence of rock layers where erosion or non-deposition has occurred, resulting in missing layers of rock. This discontinuity represents a period of time where geological processes disrupted the normal deposition of sediments.
A gap in the geological record in a body of rock is called an unconformity.
