Bedrock is a term used to describe the solid and stable rock that lies beneath the surface of the Earth. It is often composed of igneous, sedimentary, or metamorphic rocks and can be found in many different geological formations. The crossword solution for the term 'bed rock' is ORE, which stands for an ORE deposit, which is a mineral-bearing rock that can be mined for its valuable resources. ORE deposits are typically found in areas where the bedrock has been exposed to weathering and erosion, allowing the minerals to be concentrated in certain areas.
