Answer Details
Soils with well-developed profiles formed mainly under the influence of the regional climate and vegetation are said to be zonal. The term "zonal" refers to the fact that these soils are characteristic of a particular zone or region, and their properties are largely determined by the regional climate and vegetation. This type of soil formation typically occurs in areas where the climate is relatively stable and the vegetation is well-established, allowing for the development of a distinct soil profile over time. Zonal soils are often deep, well-drained, and rich in organic matter, and they may be associated with specific types of vegetation, such as forests or grasslands. In contrast, azonal soils are soils that are not well-developed due to limitations such as steep slopes, rocky terrain or recent deposition, while intrazonal soils are soils that develop due to factors such as excess moisture or high acidity that are not directly related to the regional climate and vegetation. Colluvial soils, on the other hand, are soils that have been formed through the accumulation of material that has moved downslope due to the force of gravity.
