Black soil
Old alluvial
Sandy soil
Red soil
Answer is Right!
Answer is Wrong!
The correct answer is: B. Old alluvial
The Damodar valley region of Jharkhand is a vast plain that is formed by the deposition of sediments from the Damodar River. The sediments are mostly alluvial, which means that they are made up of sand, silt, and clay. The alluvial soil in the Damodar valley region is very fertile and is used for agriculture.
The other options are incorrect because:
- Black soil is a type of soil that is rich in organic matter. It is found in the Deccan Plateau of India.
- Sandy soil is a type of soil that is made up of sand particles. It is not very fertile and is not suitable for agriculture.
- Red soil is a type of soil that is rich in iron oxide. It is found in the eastern and central parts of India.
