R bedrock
In soils with distinct soil horizons, the bottom zone is the bedrock denoted as R.
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.
The zone of leaching is found in the E horizon of soil. This horizon is characterized by the removal of minerals, organic matter, and other solutes due to the downward movement of water through the soil profile.
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.
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.

E soil horizon best describes the leaching zone, where minerals and nutrients are typically removed by percolating water.
R bedrock
The horizons of a soil profile are O horizon (organic matter), A horizon (topsoil with organic material), E horizon (zone of leaching), B horizon (subsoil with accumulation of minerals), C horizon (weathered parent material), and R horizon (bedrock).
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.
The correct order of soil horizons, from top to bottom, is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. It is important to note that not all soils have all these horizons, as they can vary depending on the specific conditions of the soil.
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.
A distinct layer or zone within a soil profile is called a horizon. Horizons are differentiated based on factors like color, texture, composition, structure, and other properties, and they play a role in understanding the soil's formation and characteristics.
