Question

How is red soil formed? Mention its six characteristics.

Answer 1

Red soil is formed by weathering of old crystalline igneous and metamorphic rocks. It is rich in iron and hence appears red in colour. In India, it is found mainly in Deccan plateau.

Red soil:

1.Seen mainly in low rainfall area.

2.Also known as Omnibus group.

3.Porous, friable structure.

4.Absence of lime, kankar (impure calcium carbonate).

5.Deficient in: lime, phosphate, manganese, nitrogen, humus and potash.

6.Colour:Red because of Ferric oxide.

7.Texture: Sandy to clay and loamy

Answer 2

Answer:

The correct answer to this question is Old crystalline igneous and metamorphic rocks weather to form red soil. It is red in color because it is iron-rich. It is primarily found in the Deccan plateau of India.

Explanation:

Given - Red soil formed.

To Find - How is red soil formed? Mention its six characteristics.

Old crystalline igneous and metamorphic rocks weather to form red soil. It is red in color because it is iron-rich. It is primarily found in the Deccan plateau of India. Ancient crystalline and metamorphic rocks, especially acid granites and gneisses, quartzitic rocks, and felspathic rocks, weather to create it. Chemically, red soil is siliceous and aluminous with free quartz as sand, but it also contains a lot of potassium and comes in a variety of textures, with loamy soil making up the majority.
