When you travel in certain parts of India, you will notice red soil. What is the main reason for this colour?
- AAbundance of magnesium
- BAccumulated humus
- CPresence of ferric oxidesCorrect
- DAbundance of phosphates
Explanation
The correct answer is C because the red color of this soil is primarily due to the presence of iron in a crystalline and metamorphic form, specifically ferric oxides. When iron in the soil undergoes oxidation or weathering, it develops a characteristic reddish tint. In its hydrated form, this soil may appear yellow. Magnesium, humus, and phosphates do not contribute to the red coloration of soil.
