The rock that breaks down into mineral fragments that form a soil is called parent rock. Different parent rocks have different chemical compositions. As a result, soils also differ in composition. Bedrock is the layer of rock beneath soil.In some cases, the bedrock is the parent rock. In these cases, the soil remains above the bedrock that weathered to form the soil.Soil that remains above its parent rock is called residual soil.Few soils are residual soils.any people think that soil is just dirt.
