* Bedrock is solid rock. It's the foundation upon which soil forms. It's typically very hard and resistant to weathering and erosion.
* Soil sediment is broken down rock. Soil is created through a process called weathering, where bedrock is broken down into smaller particles by forces like wind, rain, ice, and biological activity.
* Time is a factor. This process of breaking down bedrock takes a very long time, often thousands or millions of years.
Here's the sequence:
1. Bedrock: The solid, unweathered rock.
2. Weathering: Bedrock is broken down into smaller pieces (sediments) through various processes.
3. Soil Formation: The weathered sediments mix with organic matter and undergo other changes to form soil.
So, while bedrock is the source material for soil, it doesn't directly become the soil sediment. The bedrock is broken down into sediments, which then contribute to soil formation.
