Which factor affects soil permeability the most?
A. Soil structure
B. Clay content
C. Particle size distribution
D. Organic matter
Answer: Option C
Solution (By Examveda Team)
Particle size distribution greatly affects permeability: coarse soils (e.g., sand) allow water to pass quickly, fine soils (e.g., clay) restrict it.This Question Belongs to Geological Engineering >> Soil Mechanics
