An angular unconformity forms when older tilted or folded rock layers are eroded, creating a flat surface. New horizontal layers are then deposited on top of this surface, resulting in an angular discordance between the older and newer rock layers.
An unconformity is created when layers of sedimentary rock are eroded or worn away by natural elements like water or wind, leading to a gap in the geological record. This erosion removes previously deposited layers, and when new sediment is deposited over the eroded surface, it creates an unconformity. The resulting mismatch between the older eroded rock and the newer sedimentary layers indicates a significant period of non-deposition or erosion, highlighting changes in environmental conditions over time.
Due to faulting or folding.
rock layering is where you have one layer of old rock them a newer layer then an other newer layer.
The law of superposition states that in any undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom, while the younger layers are on top. Similarly, a laundry basket accumulates clothes over time, with newer items added on top of older ones. Just as you can determine the order of rock layers by their position, you can identify the age of the laundry pile by examining the layers of clothing—newer items will be on top, while older ones remain at the bottom.
Superposition is the principle that states that, in undisturbed strata, newer layers will be deposited over older layers; thus, in a core sample, those samples of earth and rock nearest the surface will be newer in age than those beneath them.

Is called an unconformity.

An angular unconformity is formed when there is a period of tectonic activity that causes the existing rock layers to be tilted or folded. Following this deformation, erosion occurs, removing some of the upper layers. Finally, new sedimentary layers are deposited atop the eroded surface, creating a visible angular relationship between the older, tilted strata and the newer, horizontal layers.

Factors such as wind, ice, and warder contribute to sedimentary build up. As this occurs older layers of sedimentary rock are driven lower while newer layers replace them closer to the surface.
