The Deccan Traps region exhibits extensive laterite profiles. Which factor combination is primarily responsible for the development of deep, mature laterite profiles over basalt parent rock?
- 1Rapid marine transgressions that deposit thick layers of organic-rich muds over crystalline basements
- 2Constant sub-zero temperatures and frost-wedging that cause mechanical shattering of high-silica rocks
- 3Hyper-arid conditions with high wind velocity that lead to physical disintegration and deposition of calcareous sands
- 4Intense chemical weathering under tropical monsoonal climates with alternating wet and dry seasons, promoting leaching of silica and enrichment of iron and aluminum oxides✓
Correct answer
Intense chemical weathering under tropical monsoonal climates with alternating wet and dry seasons, promoting leaching of silica and enrichment of iron and aluminum oxides
