Mountain Soil Zone in Himachal Pradesh is found between:
(A) 3000-6000 m
(B) 1500-3000 m
(C) 1000-1500 m
(D) 900-1000 m
The correct answer is (A) 3000-6000 m.
Explanation 🏔️
The soils of Himachal Pradesh are generally classified into different zones based on altitude, which directly influences climate, vegetation, and the soil formation process. The Mountain Soil Zone represents the highest of these classifications.
This zone, found between approximately 3000 and 6000 meters, is located above the tree line and is characterized by:
- Alpine pastures and meadows.
- Cold desert conditions (in regions like Spiti).
- Soils that are typically thin, shallow, and in early stages of development.
- High content of organic matter due to the slow decomposition of plant material in the cold climate.
- A texture ranging from silty loam to loam, with a dark brown color.
Analysis of Other Options
- (B) 1500-3000 m: This range corresponds to the High Hill Soil Zone, which typically has more developed forest soils like podzols.
- (C) 1000-1500 m: This is the Mid Hill Soil Zone, characterized by brown earth and reddish loam soils.
- (D) 900-1000 m: This falls into the Low Hill Soil Zone, which is dominated by alluvial and loam soils in the valleys and foothills.
