Question

Which of the following soils is formed by the disintegration of basalt?

• A. Laterite soil
• B. Regur
• C. Alluvial soil
• D. Mountain soil

Hint:

Regur soil is called "Black Cotton Soil" because it is the most suitable soil for growing cotton in India, particularly in Maharashtra and Gujarat.

Answer 1

The Correct Option is B

The question asks which type of soil is formed by the disintegration of basalt. Let's examine each option to determine which one is correct.

1. Laterite Soil: This type of soil is typically found in regions with high rainfall and high temperatures. It forms through intensive weathering and leaching of silica from the soil, not specifically from basalt. Therefore, laterite soil is not formed by the disintegration of basalt.
2. Regur Soil: Also known as black soil, regur soil is highly characteristic of volcanic regions. It is primarily composed of materials from the weathering of basaltic rocks. Hence, regur soil is correctly associated with the disintegration of basalt.
3. Alluvial Soil: This soil is formed by the deposition of sediments carried by rivers and water bodies. It is not related to basaltic rock disintegration. Alluvial soil primarily consists of sand, silt, and clay, with no volcanic origin.
4. Mountain Soil: Found in hilly and mountainous areas, this soil is derived from weathered fragments of rocks and organic material. However, it does not specifically result from the disintegration of basalt.

After examining all options, we can conclude that the soil type formed by the disintegration of basalt is Regur Soil.
