Which of the following describes the distinct nature of soil erosion commonly experienced in the sloping midland (Idanad) lateritic terrain of Kerala during high-intensity monsoons?
A. Wind deflation resulting in extensive sand dune migration
B. Sheet and rill erosion intensified by deforestation and unscientific hillside agricultural practices✓ Correct Answer
C. Saline crusting due to hyper-saline groundwater evaporation
D. Glacial scouring and tarn excavation
💡 Solution & Explanation
The sloping lateritic terrain of Kerala experiences severe sheet and rill erosion during heavy monsoon downpours, a process accelerated by deforestation and improper agricultural practices on hill slopes. Other phenomena such as wind deflation, saline crusting, and glacial scouring do not characterize the tropical humid climate and soil profile of the region. Soil conservation measures like contour bunding are crucial for mitigating this agricultural degradation.
