A. Average annual rainfall
B. Orientation of bedding planes
C. Color of rocks
D. Vegetation density
Answer: Option B
Solution (By Examveda Team)
Orientation of bedding planes is crucial because it influences potential failure planes and water seepage.Unfavorable alignment can lead to collapse or instability.This Question Belongs to Geological Engineering >> Engineering Geology For Construction
