Which Soil Horizon Is The Least Weathered Horizon And Contains Rock That Is Starting To Break Down Into Soil?
Answer:
The soil horizon that is the least weathered and contains rock that is starting to break down into soil is known as the C horizon. The C horizon is the bottom layer of the soil profile and consists of partially weathered or unweathered parent material. This layer is where the weathering process begins, as the rock gradually breaks down into smaller particles to form the soil. The C horizon is the least affected by soil-forming processes compared to other horizons and serves as the starting point for soil development.
