Which scientific approach gives the MOST information about the deep interior of Earth?
A) deep drilling of exploratory holes for science and mineral recovery (e.g., oil)
B) study of lava flows from volcanoes
C) measurement of cosmic neutrinos, which pass very easily through Earth
D) worldwide measurement of low-frequency seismic waves produced by earthquakes

Question

Quizplus · Accepted Answer

Worldwide measurement of low-frequency seismic waves produced by earthquakes provides the most information about the deep interior of Earth. Seismic waves travel through different layers of the Earth, and by analyzing how these waves are reflected, refracted, and attenuated, scientists can infer the composition, density, and physical state of materials deep within the Earth. This method has been fundamental in developing models of Earth's inner structure, including the crust, mantle, outer core, and inner core.
