• B. Three
• C. Four
• D. Five

Answer 1

The correct option is D Five

The soils of Tamil Nadu may be grouped into five types. They are:

1. Alluvial Soils: The soils develop from the weathering material transported by rivers from their catchment areas and deposited in their basins during floods.
2. Black Soils: The soils are residual soils derived from the rocks of Deccan Trap, Rajmahal Trap, ferruginous gneisses and schists under semi-arid conditions.
3. Red Soil: The soils have developed on crystalline rocks by prolonged weathering in hot climate.
4. Laterite Soils: The soils are residual soils developed on aluminum-rich rocks e.g. greisze, sandstone, granite and basaltic rocks in regions of high rainfall with alternating wet and dry seasons.
5. Forest, peat and organic soils: Forest soils develop in areas under heavy forest cover. Peat and organic soils develop in waterlogged, swampy or marshy areas.
