Q64

Which rock property affects wave velocity the most in seismic tests?

A.
Hardness
B.
Porosity
Answer
C.
Permeability
D.
Surface roughness

Answer: Option B

Solution

Answer: Option B
Solution:
Porosity affects the density and elastic properties of rock, hence impacting seismic wave velocity. Higher porosity typically reduces wave speed.
