Question

Explain different layers of soil with diagram and their properties.​

Answer 1

Explanation:

Soil has different layers, which are called horizons. These layers begin with leaf litter, and end with the bed rock. The layers are:

[i] Leaf litter- This layer is the topmost layer and consists of leaf litter and decomposed organic matter. Above this layer are the plants' shoots.

[ii] Topsoil- This layer is slightly dark in color. It is made up of humus. Seeds germinate here.

[iii] Leaching layer- This layer is light in color. It is the third layer of soil. This layer is deprived of minerals because of the process of eluviation. 

[iv] Subsoil- This layer contains mineral deposits. It gets its minerals from drips from the layer above (through process of eluviation).

[v] Regolith- This is the second last layer of soil. This has broken-up rocks from the bed rock. Plant roots and organic material are nil here.

 

[vi] Bed rock- The last comes the bed rock. This is made up of unweathered rocks and is below all the other layers.
