Umm... let's see.
The top layer is top-soil.
The middle layer is sub-soil.
The bottom layer is parent rock....
I think you've got the answer......
;-) you're welcome!
The bottom layer of rock in a geologic sequence is usually called the basement layer.
The soil layer of rock beneath the soil is called bedrock. It is the solid rock layer that underlies the loose topsoil and subsoil layers.
The layer of soil is called the topsoil, which is the uppermost layer of soil that contains most of the organic matter and nutrients that plants need to grow. It is typically the darkest and richest layer of soil, where most plant roots are found.
The layer of solid rock below the soil is called bedrock. It is composed of consolidated rock that serves as the foundation for the soil layer above it.
The topsoil layer contains the most fertile soil. It is the upper layer of soil that is rich in organic matter, nutrients, and microorganisms, making it ideal for plant growth.
The 4th layer of soil >.<
The bottom layer of rock in a geologic sequence is usually called the basement layer.
The topsoil is the finest soil layer. Soil 'layers' are called horizons.
There are four layers and the four layers are top layer called the organic layer, Upper soil layer, middle soil layer, and the last one is lowest layer.
In a normal sequence (ie one that has not been tectonically deformed) the oldest layer is the lowest layer - so the one at the base of the sequence is the oldest. This is called the "law of superposition".
The soil layer of rock beneath the soil is called bedrock. It is the solid rock layer that underlies the loose topsoil and subsoil layers.

you find them in the lowest soil.
The top layer of soil is the most fertile layer. It is the best for growing crops.
layer A- the mineral rich soil layer B-the rocky mineral-producing layer layer C- the place wher rocks and soil meet layer D- the dense rocky chunks of soil layer E- pure rock layer
The bottom layer was depostied first and is the oldest layer.
the first layer is "DIRT" the second layer is "DIRT" the third layer is "DIRT" and the fourth layer is "DIRT"
