how is red soil formed and what are its characteristics
Answers
Explanation:
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 is formed by the weathering of ancient crystalline and metamorphic rocks, particularly acid granites and gneisses, quartzitic rocks, and felspathic rocks. Chemically, red soil is siliceous and aluminous, with free quartz as sand, but is rich in potassium, ranging from sand to clay with the majority being loamy
