Question

When deeper layers have increasingly greater density, the seismic refraction method is fast.

(a) False

(b) True

I have been asked this question in an interview for internship.

I need to ask this question from Geophysical Methods topic in section Stabilisation of Soils, Site Investigation and Sub – Soil Exploration of Geotechnical Engineering II

Answer 1

Right option is (b) True

Easiest explanation: The seismic refraction method is fast and a reliable method in establishing profiles of different strata when the deeper layers have increasingly greater density and thus higher velocities.
