Question

Which of the following statements regarding the Deccan Trap region is correct?

1. The region consists of sedimentary rocks formed by river deposition.

2. It has black soil due to volcanic origin.

3. The rocks in this region are igneous in nature.

• A. 1 & 2
• B. 2 & 3
• C. 1 & 3
• D. All are correct

Answer 1

Answer:

B. 2 & 3

• Igneous rocks, not sedimentary: The Deccan Traps are made up of multiple layers of solidified flood basalt - these are igneous rocks formed from volcanic lava flows, not sedimentary rocks from river deposition. The first statement is incorrect.

• Black soil of volcanic origin: The region is famous for its black cotton soil (also called regur soil). This black soil is formed from the weathering of basaltic lava and is rich in minerals like calcium carbonate, magnesium, potash, and lime. This statement is correct.

• Igneous rock composition: The rocks in this region are indeed igneous in nature, specifically basaltic rock formed through volcanic activity. This statement is correct.
