In geology, what term refers to the solid rock layer beneath the earth's surface?

Explanation:
Bedrock is the solid rock that lies beneath soils and other loose surface material. It represents the rock that hasn’t been weathered into debris and carried away, sitting beneath surface coverings. Earth’s outer shell is called the crust, but the layer directly under surface materials—undisturbed solid rock—is bedrock, with the mantle and core located much deeper inside. So, bedrock is the best term because it specifically identifies the continuous solid rock beneath the surface layers you interact with.
