"Geophysical tools to obtain data to interpret physical structure of the earth." This item is a little vague - can you supply a list of tools, or at least an idea of what kind of tools, that should be covered?
By far the most important geophysical tool for revealing earth's structure is seismography. Students should be familiar with both natural and controlled-source methods, how they work, and what they reveal, at a minimum. Additional important tools include magnetometry, gravimetry, and ground-penetrating radar. There are more, but these are the ones most likely to be assessed in the event.
