Here's the breakdown:
* Bedrock: This is the solid, unweathered rock that lies beneath the soil and other loose sediments. It's the foundation upon which everything else sits.
* Soil: This is a mixture of weathered rock, organic matter, water, and air. It forms on top of the bedrock through processes like weathering and erosion.
Think of it like a cake:
* Bedrock: The base of the cake, the solid layer.
* Soil: The frosting and filling, the loose and crumbly layer on top.
So, the layers of rock above soil are actually part of the regolith, which includes all the loose, unconsolidated material that covers bedrock.
