Here's a breakdown of the typical soil profile layers:
* O horizon: This is the topmost layer, composed of organic matter like leaves, twigs, and decomposing plant and animal material.
* A horizon: Also known as topsoil, this layer is a mix of mineral soil and organic matter. It's where most plant roots grow.
* E horizon: This layer is characterized by the loss of minerals and organic matter due to leaching. It's typically lighter in color than the A horizon.
* B horizon: This is the subsoil, where minerals and organic matter from the A and E horizons accumulate.
* C horizon: This layer consists of weathered bedrock and is the transition zone between soil and parent rock.
* R horizon: This is the bedrock layer.
Note: Not all soil profiles have all of these layers. The presence and development of each layer depend on factors like climate, vegetation, and parent material.
