Q2
What is the primary physical property measured in the seismic refraction method?
A.
Electrical resistivity
B.
Density
C.
Seismic wave velocity
AnswerD.
Magnetic susceptibility
Answer: Option C
Solution
Answer: Option C
Solution:
Seismic refraction measures the velocity of seismic waves through subsurface materials.This helps determine layer depths and types of rocks or soils based on their stiffness.
