Answer 1

Answer:

Theses are the different layers of soil:

1) Organic - The organic layer (also called the humus layer) is a thick layer of plant remains such as leaves and twigs.

2) Topsoil - Topsoil is considered the "A" horizon. It is a fairly thin layer (5 to 10 inches thick) composed of organic matter and minerals. This layer is the primary layer where plants and organisms live.

3) Subsoil - Subsoil is considered the "B" horizon. This layer is made primarily of clay, iron, and organic matter which accumulated through a process called illuviation.

4) Parent material - The parent material layer is considered the "C" horizon. This layer is called the parent material because the upper layers developed from this layer. It is made up mostly of large rocks.

5) Bedrock - The bottom layer is several feet below the surface. The bedrock is made up of a large solid mass of rock. ............

$\textbf{The following are the layres of the soil :}$

◾ Top most humus layer :

This layer contain dead and decaying matter in the soil. This made the soil fertile. More thicker this layer more the soil fertile. Forests has a thick humus layer. Usually this is thinnest layer of soil. It is A horizon.

◾ Subsoil weathered rocks, sand and silt clay :

This layer has a very little amount of humus content . This has fine sand particle. Usually this layer is thicker than humus layer. It is B horizon of soil

◾ Substratum weathered parent rock material :

This layer has no humus content. This contain rough sand particles and pieces of parent rock. It is C horizon of soil.

◾Unweathered parent bed rock :

This layer has no humus content and fine soil. It mainly contain Unweathered parents rocks. It is D horizon of soil.
