Difference between GPR from seismic

Click For Summary
GPR (Ground Penetrating Radar) utilizes electromagnetic waves, making it ideal for shallow, high-resolution surveys, while seismic methods employ seismic waves suitable for larger-scale investigations. The fundamental difference lies in the types of waves used: GPR reflects at high permittivity contrasts, whereas seismic techniques reflect at high acoustic impedance contrasts. Both methods can be complementary in geophysical surveying, each offering unique advantages based on the specific properties being examined. GPR excels in detailed subsurface imaging, while seismic methods are effective for broader geological assessments, including deep Earth studies. Understanding these differences enhances the application of both techniques in geophysical research.

(1) What would you consider to be the qualitative difference between GPR (Ground Penitrating Radar) and Seismic?

(2) How is the GRP similar and different from seismic

GPR uses electromagnetic waves, seismic uses seismic waves. GPR is better for shallow, high resolution surveys; seismology is better for surveys at larger scales, from small refraction surveys up to and beyond global scales sampling the Earth's inner core (ever heard of helioseismology?). Electromagnetic waves are most notably reflected at high permittivity contrasts, whereas seismic waves are most notably reflected at high acoustic impedance contrasts - the two techniques depend on different geophysical properties and therefore can be complementary in geophysical surveying.
 
I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
