The Physics of the Earth

  • A. H. Cook


I wish in this first section to explain how we may use methods and ideas of physics to arrive at models that represent the interior structure of the Earth. I say models because we cannot observe the interior directly; we observe effects of the interior at the surface and we must infer the structure of the interior from what we see at the surface. This is the key problem of method in the physical study of the interior of the Earth; an extensive body of theory has been developed to discuss it, and the methods adopted to construct interior models from surface observations are called Inversion Methods. In general there is a whole range of models that fits the observations and one aim of geophysical studies is to specify the uncertainties in our understanding of the interior of the Earth.
