1 Answer

Answer :

(1) humus Explanation: The distribution of mountain soils is subject mainly to a vertical (elevation) zonation; the soils change with ascent into the mountains depending on changes in climatic conditions. Most mountain soils form on very steep slopes where, as a result of denudation processes, their shallowness, gravel-like quality, and wealth of primary minerals may be observed. Mountain soils are those which are found in depressions and valley basins or on slightly inclined mountain slopes. It consists of sandstones, clay, shales and limestones. It has the maximum humus content and is thus, very fertile. It is found in Himalayan regions and north-east India.
