Gaps in rock layers that develop when agents of erosion remove existing rock layers are known as unconformities.
Erosion of the missing layers.
Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations.While erosion is a natural process, human activities have dramatically increased (by 10-40 times) the rate at which erosion is occurring globally. Excessive erosion causes problems such as desertification, decreases in agricultural productivity due to land degradation, sedimentation of waterways, and ecological collapse due to loss of the nutrient rich upper soil layers. Water and wind erosion are now the two primary causes of land degradation; combined, they are responsible for 84% of degraded acreage, making excessive erosion one of the most significant global environmental problems we face today.
Wind can create alterations in the surface layers of rocks, and wind is one cause of erosion.
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.

The processes of weathering and erosion, which were caused by wind, ice, and water, are responsible for exposing the dinosaur fossils at Dinosaur National Monument. Weathering is the process of rock being broken into sediments. Erosion is when those sediments are carried away by wind and water.

Arches mountains are formed through a process called erosion, where softer rock layers underneath harder rock layers are slowly worn away by forces like wind and water, leaving behind unique structures with curved or arched appearances. Over time, this erosion can create natural arches and bridges in the mountains.
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.
