bedrock
The topsoil layer is typically least similar to the underlying rock, as it is a combination of organic matter, minerals, and microorganisms that have been weathered and broken down over time. This layer tends to have a different composition and structure compared to the solid rock beneath it.
The topsoil layer is typically least similar to the underlying rock because it is composed of organic matter, minerals, and nutrients that have been weathered and mixed over time. This layer is influenced by factors such as climate, vegetation, and erosion, making it different in composition from the solid rock below.
I believe the answer is water.
The deeper layer.
rock
The one closest to the surface because rock layers are laid down one on top of another.
Pleistocene rock layer
The top layer. The top layer of any sedimentary rock is most likely the newest in geologic time.

The answer is magma.
basalt
The layer that contains the most humus and smaller rocks is the topsoil layer. Topsoil is the uppermost layer of soil that is rich in organic matter, such as humus, and contains smaller rock particles that have undergone weathering. It is the most fertile layer of soil and is crucial for plant growth.
