Stone beneath soil
Bedrock is the solid rock that lies beneath soil and looser surface material.
Figuratively, bedrock is the fundamental basis of something—the deepest, most stable foundation: Trust is the bedrock of any relationship.
As an adjective, bedrock describes what is most basic or essential: bedrock principles, bedrock values.
