A single layer with consistent characteristics is referred to as a stratum.
What else can I help you with?
Sedimentary rock made from layers of dead plans is called?
If the layer is of dead plants, it is a compressed layer known as a coal seam.
The fundamental sedimentary rock unit is called?
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.
Where is the youngest layer of sedimentary rock found?
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.
To date a sedimentary rock layer between two igneous rock units geologists use radiometric dating and assume that the sedimentary layers are?
Geologists use radiometric dating of the igneous rock units above and below the sedimentary layer to establish a time range for the sedimentary rock. They assume that the sedimentary layers are younger than the underlying igneous rock and older than the overlying igneous rock, based on the principle of superposition. This allows them to estimate the age of the sedimentary layer by determining the ages of the surrounding igneous rocks.
What feature is formed when a sedimentary rock overlies a nonsedimentary rock layer?
Unconformity
What layer is sedimentary rock in?
sedimentary layer ㅡㅡ
What is the name of the bottom rock layer?
The bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
What do geologists call a single layer of sedimentary 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.
What is a layer of sedimentary?
a layer of rock
The fundamental sedimentary rock unit is called a?
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.
What sedimentary rock is formed from thin layer of clay compacted very tightly together?
This is Shale, a Sedimentary rock.
What feature is formed when a sedimentary rock layer overlies a nonsedimentary rock layer?
Unconformity

Type of rockformed from sediments called?
A rock formed for sedimentary deposits is called a sedimentary rock. A sedimentary rock which has then undergone metamorphism is called a meta-sediment.
What is the makeup of the youngest layer of sedimentary rock?
Clay
