A single layer with consistent characteristics is referred to as a stratum.
If the layer is of dead plants, it is a compressed layer known as a coal seam.
The fundamental sedimentary rock unit is called a stratum or a bed. It is a relatively thin layer of sedimentary rock that is distinguishable from overlying and underlying layers based on characteristics such as composition, color, and texture. Stratigraphy, the study of rock layers and layering, relies on the identification and correlation of these rock units.
The youngest layer of sedimentary rock is typically found at the top of a sedimentary rock sequence, as it is the most recently deposited layer. This layer is usually exposed on the Earth's surface, such as in river valleys or coastal areas, where erosion may have removed older layers above it.
Unconformity
The layer of rock formed from sediments deposited on land is called sedimentary rock. This type of rock forms from the accumulation and compression of sediments, such as sand, silt, and clay, over long periods of time. Examples of sedimentary rocks include sandstone, shale, and limestone.
sedimentary layer ㅡㅡ
The bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
A single layer of sedimentary rock is called a "bed." Beds can vary in thickness and can be identified based on their distinct characteristics such as composition and sedimentary structures.
a layer of rock
The fundamental sedimentary rock unit is called a "bed." It refers to a layer of sedimentary rock that is distinguishable from the layers above and below it based on characteristics such as composition, grain size, and sedimentary structures. Beds are building blocks of larger sedimentary structures like formations and sequences.
This is Shale, a Sedimentary rock.

Clay
A rock formed for sedimentary deposits is called a sedimentary rock. A sedimentary rock which has then undergone metamorphism is called a meta-sediment.
