What role can geophysics play in archaeological research?

Question

Quizplus · Accepted Answer

The Answer is Geophysical methods allow a researcher to see what is below the surface of the ground without digging it up. It cannot show exactly what is there and the data needs to be interpreted by experienced people, but it can help researchers focus their excavations on areas that seem to be related to human activities as opposed to those areas that are not involved. It also allows complete survey of large areas relatively quickly. Two of the techniques used are Ground Penetrating Radar (GPR) and magnetometry, and others include electromagnetic and resistivity/conductivity. GPR sends out an electromagnetic pulse, which is either absorbed on reflected based on the internal structure of the ground. Magnetometry detects magnetic features or objects that cause changes in the earth's magnetic field.
