Question

If so, how do soils developed directly from bedrock differ from soils
developed on unconsolidated material, if at all?​

Answer 1

When referring to such soil, it is better to be specific and say “soil developed on unconsolidated material,” because that distinguishes it from soil developed on bedrock. ... Quartz-poor material, such as shale or basalt, generates soils with little sand. Parent materials provide important nutrients to residual soils.

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 can be carried away from its parent rock by wind, water, ice, or gravity.
