Arrange the following soil particles in descending order of their diameter. (A) Clay (B) Silt (C) Fine sand (D) Coarse sand Choose the correct answer from the options given below :
Understanding Soil Particle Size Order
Soil particles are categorized based on their size (diameter). This classification is fundamental in soil science and influences soil properties like water retention and aeration.
Soil Particle Diameter Hierarchy
The standard classification ranks soil particles by their diameter, from largest to smallest. The primary textural classes relevant here are:
- Coarse sand (Largest among the options)
- Fine sand
- Silt
- Clay (Smallest among the options)
Thus, the order from largest diameter to smallest diameter is: Coarse sand > Fine sand > Silt > Clay.
Arranging the Given Soil Particles
The question requires arranging the following soil particles in descending order of their diameter:
- (A) Clay
- (B) Silt
- (C) Fine sand
- (D) Coarse sand
Applying the known hierarchy:
- Largest: Coarse sand (D)
- Next largest: Fine sand (C)
- Next largest: Silt (B)
- Smallest: Clay (A)
The descending order is therefore (D), (C), (B), (A).
Final Answer Selection
The correct sequence representing the descending order of soil particle diameters is (D), (C), (B), (A).
