What are 5 layers of sediment?

The five layers of sediment typically refer to the stratigraphic layers found in sedimentary rock formations. These layers include: 1) Gravel and coarse sediments at the bottom, often deposited by high-energy environments; 2) Sand, which accumulates in moderate-energy conditions; 3) Silt, representing quieter water environments; 4) Clay, formed in low-energy settings; and 5) Organic-rich layers, where decaying plant and animal matter accumulates. Each layer reflects changes in environmental conditions over time.
