To what extent temperature and precipitation are the most important factors that determine soil properties? (Answer in 150 words) 10 marks
Introduction
Soil is part of topography of an area indicates lithosphere zone in geographic zonation.

Main Body
Diagram showing zonation of soils across India: Piedmont soil, Alluvial soil, Sandy soil, Black soil, Laterite soil, Red soil. Temperature: High temperature leads to good nutrient rate of extraction
Continuation: Temperature factors: red soils in high insolation area; black soil owing to ground temperature (basalt-deccan trap); leaching in tropical soils. Rain factors: coastal soils due to sand & saline intrusion; rain leads to sheet erosion on mountains; lack of fertility in evergreen forests due to continuous rains
Conclusion
Hence both factors must be studied for soil health cards, agro-climatic zonation & soil stability to avoid land slide.
