Question

What are the main characteristics of the R horizon?

Answer 1

Hint: The soil is the highest layer of the world's outside, basically made out of natural minerals and rock particles that help life. A soil profile is a vertical cross-segment of the soil, made of layers running corresponding to the surface. These layers are known as soil skylines.

Complete answer:
The Soil Layers-
A progression of skylines or layers of soil layered one on top of the other makes up the soil profile. The letters O, A, E, C, B, and R are used to refer to these layers or skylines.
The R-Horizon-
It's a solidified and compacted plate. Here, various types of rocks such as stone, basalt, and limestone have been discovered. Its characteristics change depending on the stone that makes it up! It cannot be regarded as a skyline because it contains solidified content that has not been endured and, as a result, has not been passed by paedogenic steps.
Additional Information:
The O-Horizon-
The O skyline is the upper layer of the dirt which is basically made out of natural materials like dried leaves, grasses, dead leaves, little shakes, twigs, surface life forms, fallen trees, and other disintegrated natural matter. This skyline of soil is regularly dark earthy colored or dull earthy colored in shading and this is essentially a direct result of the presence of natural substances.
The A-Horizon or Topsoil-
This layer is wealthy in natural material and is known as the humus layer. This layer comprises both natural matter and other deteriorated materials. The dirt is delicate and permeable to hold sufficient air and water.
In this layer, the seed germination happens and new roots are created which develops into another plant. This layer comprises of microorganisms like worms, growths, microscopic organisms, and so forth
The E-Horizon-
This layer is made out of supplements filtered from the O and A skylines. This layer is more normal in forested zones and has lower earth content.
The B-Horizon or Subsoil-
It is the subsurface skyline, present just beneath the dirt or more the bedrock. It is relatively harder and minimal than dirt. It contains less humus, solvent minerals, and natural matter. It is a site of statements of specific minerals and metal salts like iron oxide.
The C-Horizon or Saprolite-
This layer is without any natural matter and consists of broken bedrock. This layer is otherwise called saprolite. The land material present in this zone is established.

Note:
The B horizon is a layer that holds sufficient water than the dirt and is lighter earthy coloured because of the presence of mud soil. The dirt of skyline An and skyline B is regularly blended while furrowing the fields.
