Answer:

The B horizon soil layer comprises weathered bedrock material which is not yet leached or had significant accumulation.

Explanation:

The B horizon is called the subsoil and it contains the weathered rock and less organic matter. It is also referred to as the area of accumulation. The minerals and clay from the upper layers when leached accumulate and settle in this layer.

The accumulation process of material from the top layers is called illuviation. The accumulated material popular in B horizon include silicate, iron, gypsum, clay, humus, aluminum, carbonates, and silica. B horizon is two to three feet deep.
