Unconformities are either a feature of deposition or igneous extrusions; and are not as a result of erosion, yet the material making one up may be a product of erosion.
Gaps in rock layers caused by erosion are known as unconformities. Unconformities represent missing sections of geological time between layers and can be caused by processes such as weathering, erosion, or tectonic activity. They can provide valuable insights into the history of the Earth's surface and the processes that have shaped it over time.
Possible sources of unconformities include erosion, deposition of sediment, tectonic movement that tilts or folds rock layers, and changes in sea level that expose rock layers to weathering and erosion.
Unconformities can be caused by erosion, tectonic activity, or a gap in the geologic record due to non-deposition or removal of sedimentary layers. They represent interruptions in the rock record, often indicating periods of uplift and erosion before deposition resumes.

Missing rock layers are known as unconformities. Unconformities represent gaps in the geologic record where there is a discontinuity in the sequence of rock layers, often due to erosion or non-deposition.
Unconformities represent missing gaps or breaks in rock layers, where sedimentation was not continuous. They are caused by erosion or non-deposition, resulting in a discontinuity in the geological record. Unconformities can indicate periods of tectonic activity or changes in sea level.
There are three main types of unconformities: angular unconformity, disconformity, and nonconformity. These unconformities represent gaps in the geologic record where erosion and non-deposition have occurred.
Gaps in rock layers are called unconformities. Unconformities represent periods of time where deposition of sediment ceased and erosion occurred before deposition resumed, creating a gap in the geological record.
The three main types of unconformities are angular unconformities, nonconformities, and disconformities. Angular unconformities are where older rocks are tilted or folded before younger sediment is deposited, nonconformities are between younger sedimentary rocks and older igneous or metamorphic rocks, and disconformities are gaps in the rock record where layers are missing due to erosion.
Unconformities are gaps in the rock record where layers of sedimentary rock are missing due to erosion or non-deposition. They represent periods of time where there was no sedimentation or where previously deposited rocks were eroded away before new layers were added on top. Unconformities provide important evidence for geologic events and changes in Earth's history.
