The A horizon is the top layer of soil, where most organic matter accumulates and plant roots grow. The R horizon is a layer of partially weathered bedrock underneath the soil layers. The A horizon develops from the weathering of the R horizon over time.

How are the C and R Horizons related?

The C horizon is the unconsolidated parent material from which the R horizon (bedrock) forms over time. The R horizon is a consolidated layer of rock that lies beneath the C horizon. Both horizons are part of the soil profile, with the R horizon being the deepest layer.


What horizon is a composed of unweathered bedrock?

A horizon composed of unweathered bedrock is called the R horizon. This horizon is commonly found in areas where there is very little to no weathering, or soil development. The R horizon is essentially the underlying bedrock that lies beneath the soil layers.


What is the correct order of the different soil horizons?

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.


How are soil horizons ordered from the top of the profile to the bottom?

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.


Name All the horizons of a soil?

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).
