Here's a breakdown of soil layers:
* O Horizon (Organic Layer): This is the topmost layer, composed of decaying plant and animal matter.
* A Horizon (Topsoil): Rich in organic matter, minerals, and nutrients. It's where most plant roots grow.
* B Horizon (Subsoil): Contains less organic matter and more clay, minerals, and weathered rock.
* C Horizon (Parent Material): This layer is made up of partially weathered rock fragments that are the source of the soil above.
Bedrock is the solid rock that underlies the soil layers. It's usually impenetrable to plant roots and can vary in depth depending on the geological history of the area.
