soil
The topmost rock layer is the one that was deposited last, as rock layers are typically deposited in a vertical sequence with the oldest layers at the bottom and the youngest layers at the top.
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.
Before a rock layer can be deposited, the area must undergo erosion and weathering. This breaks down existing rocks into sediment which can then be transported and deposited in a new location. The process of deposition occurs when the sediment settles into a new location and forms a layer over time.
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.
