The "Solid Earth" theme includes internal geophysics, geodynamics, geodesy, as well as the effects of the dynamics of the Solid Earth on the external envelopes.
The use of the satellite data improve the knowledge both on a static and a dynamics level of the system Earth.
So, this theme, by using satellite data (magnetism, gravimetry, geodesy, surface imaging), complementary of those in situ, place importance on:
- understand the history of the Earthdecipher
- the structure of the inside of the Earth, from the surface to the center of the coreexplain
- the phenomena which occur in the mantle and
- the coreanalyze the part of volcanism, tectonics, erosion on climate and biodiversityunderstand earthquakes.
