Here's why:
* Bedrock is solid, unweathered rock. It's too dense and compact to support plant life.
* Soil is a mixture of broken-down rock, organic matter, air, and water.
* Weathering and erosion are the key processes that break down bedrock into smaller particles, creating the foundation for soil.
* The decomposition of organic matter (like dead plants and animals) adds nutrients and structure to the soil.
So, bedrock is the parent material that, over time, is transformed into soil through the processes of weathering, erosion, and organic matter decomposition.
