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
Pleistocene rock layer
The one closest to the surface because rock layers are laid down one on top of another.
The top layer. The top layer of any sedimentary rock is most likely the newest in geologic time.
The top layer. The top layer of any sedimentary rock is most likely the newest in geologic time.
The answer is magma.
The C horizon is the layer of a soil profile that forms first from the bedrock. It is the underlying layer that contains weathered rock fragments and shows the least amount of soil development.
