That's a good question! While it's true that bedrock is a solid layer of rock, it's not always directly under the soil. Here's why:

* Bedrock is the foundation: Bedrock is the solid, unweathered rock that forms the foundation of the Earth's crust. It's what everything else sits on top of.

* Soil is a layer: Soil is formed from the weathering and breakdown of bedrock, along with organic material. It's a separate layer that sits on top of bedrock.

* Depth varies: The depth of soil varies widely depending on location, climate, and other factors. In some areas, bedrock may be very close to the surface. In others, it can be hundreds or even thousands of feet below the surface.

So, to answer your question more accurately:

Bedrock is the solid rock layer that is the base of the Earth's crust. While it's often below the soil, it might be very close to the surface or buried deeply, depending on the location.
