It is usually due to erosion of lack of deposition.

What is an unconformity what can it tell you?

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...


When a layer or several layers of rock are missing from a rock layer sequence this is called a what?

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.

When a layer or several layers are missing from a rock-layer what is this called?

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.

Which New York State index fossil may have been present in a rock layer that is missing due to the 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.

What is a surface that represents a missing part of the geologic column called?

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.


A disconformity is an erosional unconformity with parallel beds or strata above and below?

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.


A gap in the sequence of rock layers is a?

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.


What is a gap in the geological record preserved in rock called?

A gap in the geological record in a body of rock is called an unconformity.
