The bottom horizon in a soil profile that contains only partly weathered rock is called the C horizon. In this horizon, the rock is partially weathered and has started to break down into smaller particles, but has not fully transformed into soil yet.
Soil horizons are ordered from top to bottom as O, A, E, B, C, and R horizons. The O horizon is the top organic layer, followed by the A horizon of topsoil. The E horizon is a zone of leaching, the B horizon contains minerals leached from above, the C horizon consists of partially weathered parent material, and the R horizon is unaltered bedrock.
The bottom zones in soils with distinct soil horizons are called the C horizon. This horizon typically contains weathered parent material and has limited biological activity compared to the upper horizons.
The bottom zone of a soil horizon is called the 'C horizon'. It is also known as the parent material, as it is mostly made up of partially weathered rock or sediment from which the soil has developed. The C horizon typically contains less organic matter and nutrient content compared to the overlying horizons.
The bottom zone in soils with distinct soil horizons is known as the C horizon. This layer is located below the B horizon and consists of partially weathered rocks and minerals. The C horizon is typically the least weathered and closest to the parent material.
In soils with distinct soil horizons, the bottom zone is the bedrock denoted as R.

A well-developed soil profile consists of distinct layers or horizons: O horizon (organic material), A horizon (topsoil rich in organic matter and nutrients), E horizon (zone of leaching), B horizon (subsoil with accumulation of minerals), and C horizon (weathered parent material). These horizons form through various soil-forming processes over time, influencing soil fertility and structure.
The correct order of soil horizons from top to bottom is O, A, E, B, C. The O horizon is organic matter on the surface, the A horizon is topsoil with organic material mixed with mineral particles, the E horizon is a zone of leaching, the B horizon is subsoil with accumulated minerals, and the C horizon is weathered parent material.
Solid rock is being weathered into soil in the bedrock layer of the soil profile, which is located at the bottom below the subsoil and topsoil layers. Weathering processes such as physical (freeze-thaw cycles) and chemical (acid rain) weathering act on the solid rock over time, gradually breaking it down into smaller particles that mix with organic matter to form soil.
The individual layers of soil, from top to bottom, are the O horizon (organic matter), A horizon (topsoil), B horizon (subsoil), C horizon (weathered parent material), and bedrock. Each layer has distinct characteristics and composition that influence soil fertility and productivity.
The 6 layers of soil from top to bottom are: 1. Organic layer (O horizon) - decomposing plant matter, 2. Topsoil (A horizon) - mixture of minerals, organic matter, and living organisms, 3. Eluviated layer (E horizon) - leached of minerals and clay, 4. Subsoil (B horizon) - accumulation of minerals and clay, 5. Parent material (C horizon) - partially weathered rock, and 6. Bedrock (R horizon) - unweathered rock.
