Concept:Leaching removes soil nutrients when heavy rain washes them away, reducing fertility.
Explanation:Tropical rains are very heavy and frequent.
Laterite soil forms in such hot, wet tropical regions.
These rains cause intense downward movement of water through the soil.
This process, called leaching, washes out soluble plant nutrients.
Laterite soil is especially poor in nutrients after this loss.
This makes laterite soil less fertile than other tropical soil types.
Answer:B. Laterite soil
