Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is often used in archaeology to detect buried features, such as walls, foundations, and artifacts. However, GPR is limited in its ability to detect small buried features, as the radar waves can only penetrate a few meters into the ground.
