1. Erosion: Weathering and erosion break down existing rocks into smaller pieces (sediments) like sand, silt, and clay.
2. Transportation: These sediments are then carried away by wind, water, or ice.
3. Deposition: When the transporting forces lose energy (like a river slowing down), the sediments settle and are deposited in layers.
4. Compaction: Over time, the weight of new sediments presses down on the older layers, squeezing out water and air, compacting the layers together.
5. Cementation: Dissolved minerals in the water between the sediments crystallize, acting like glue and binding the sediments together to form solid rock.
The Canyon:
The canyon itself is formed by erosion over long periods, often by rivers cutting through the layered rock. As the river carves its path, it exposes the layers of rock that were formed by sedimentation.
Important Note: While sedimentation is the primary process forming the rock layers, these layers may also undergo further changes like tilting, folding, or faulting due to tectonic activity, which can add complexity to the canyon's geological story.
