Peat
An organic layer refers to a layer of organic material, such as decaying plant matter or humus, that accumulates on the surface of soil or sediment. This layer is important for nutrient cycling, soil fertility, and supporting diverse plant and microbial life in ecosystems.
i think its sediment
No, the organic layer is not always on top of the aqueous layer. The layering depends on the relative densities of the organic and aqueous phases. The less dense layer will be on top.
When organisms died in a river or stream of some sort, they are covered in a layer of sediment, as time gos by the sediment hardens and is covered by another layer of sediment and so on.
sediment gathers up then the water in the sediment starts to evaporate. Compaction and Cementation happens then forms layer after layer.

its the fequair layer
Organic layers are part of the soil.
An example of an organic sediment is diatomaceous earth, which is made up of the microscopic remains of diatoms. Other examples include peat, coal, and oil shale.
The layer that contains the most organic material in the diagram is the top layer, known as the O horizon or organic horizon. This layer is made up of decomposing organic matter such as leaf litter and other plant debris.
Sediment is made from clay, gravel, some organic matter, weathered limestone and basalt.
