Earth Physics

The first sessions are devoted to reviewing the mathematical tools that will be used in the module. The course then consists of three parts: geothermics, gravimetry, and geomagnetism. The approach developed combines theoretical and practical approaches. Particular attention is paid during practical work to measurement and error estimation.

Hourly volumes:

CM: 15

TD: 30

TP: 9

 The depths of the Earth are largely inaccessible through direct observation. The aim of this module is to complement the seismological approach taught in^{the second} year of the bachelor's degree by presenting additional geophysical tools that provide a better understanding of our planet's internal dynamics. Measurements used to image the near surface are also presented.
