Physics of the Earth

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

Hourly volumes:

CM : 15

TD : 30

TP : 9

The depths of the Earth are largely inaccessible by direct observations. The objective of this module is to complement the seismological approach taught in the^2nd year of the degree course, by presenting complementary geophysical tools that allow a better understanding of the internal dynamics of our planet. Measurements allowing to image the near surface are also presented.
