Gaps in rock layers that develop when agents of erosion remove existing rock layers are known as unconformities.
Erosion of the missing layers.
The formations that are sandwiched between layers of existing rock formations called sills. Another formation between layers is called laccoliths.
Wind can create alterations in the surface layers of rocks, and wind is one cause of erosion.
A type of clay which is subject to the same stress as in the past. Explanation: When clay particles are deposited by deposition agents like river,sea and others, layer after layers are deposited with time which induces stresses in the claylayer below, if the deposited layers are not eroded the stress will remain same without any change and hence will be called normally consolidated clay as oppose to Over consolidated clay in which erosion of the top layers has taken place which resulted in the stress relaxation or reduction.

An unconformity is the contact between two layers representing a gap in the geologic record, usually from the erosion of the layers which would normally be expected to appear.
erosion
Rock layers can be uplifted by tectonic forces, such as the movement of tectonic plates converging, diverging, or sliding past each other. This can create pressure, folding, and faulting in the crust, causing rocks to uplift. Erosion can also remove overlying material, exposing deeper rock layers and causing uplift.

You learn that expose rock layers are the evidence that there was erosion and disturbances going on in that area.
Wind can create alterations in the surface layers of rocks, and wind is one cause of erosion.
Three layers develop in an embryo .

erosion by water
Due to missing layers in the rock strata caused by erosion.
