Scientists search for fossil fuels in many ways. sending a sound wave into the ground (by exploding dynamite, thumping the ground with a large weight, or using an electric vibrating machine) and measuring its return to the surface at receiving stations is called surveying.
a) dynamite
b) destructive
c) seismic
d) sonar
e) geologic

C) seismic  

Explanation:

The word seismic comes from a Greek word that means "shaking", as in an earthquake.

For example, a vibrating truck can shake the ground. The sound waves are reflected and refracted by various ground layers. They are recorded by an array of sensitive detectors, and the speed and intensity of the seismic waves indicate what lies below.

A) is wrong. However, dynamite explosions are often used as the sound sources in seismic surveys.

B) and E) are wrong. There are no such things as destructive or geologic surveying.

D) is wrong. Sonar surveying measures the depth of the water and detects objects on the bottom, but it does not penetrate the seafloor.
