Q. Which of the following Soils is/are zonal Soil?
1. Desert Soils
2. Red Soils
3. Laterite Soils
Select the correct answer using the codes given below:
Answer: D
Notes:
The Soils can be classified on the basis of dominating factors:
Zonal Soil – These soils occur in broad geographical areas or zones.
- They are influenced more by the climate and vegetation of the area rather than the rock-type.
- They are mature, as a result of stable conditions over a long period of time.
- For example – red soils, black soils, laterite soils, desert soils etc.
Azonal Soil – It is that soil which has been developed by the process of deposition by the agents of erosion.
- It means that it has been made by the fine rocky particles transported from the far-off regions.
- These are immature soils and lack well-developed soil profiles.
- This may be due to the non-availability of sufficient time for them to develop fully or due to the location on very steep slopes which prohibits profile development.
- For Example – alluvial and loess soils.
