Basic physics, basic geology.
In theoretical classes, subjects are introduced, discussed, and elaborated upon. At each class, a mini-test is proposed, whose solution contributes to the final grading. In theoretical-practical classes the students solve problems related to the previously lectured theoretical subjects.
Upon completion of this curricular unit the student must have sound knowledge on gravimetry, geomagnetism and seismology, on Earth and the planets and larger satellites of the Solar System. Such knowledge will be sufficient as a basis to begin graduate work in geophysics or planetary sciences; apply for internships in geophysical companies (in the specialties of gravimetry and magnetometry) or space agencies; teach subjects of geophysics and planetary sciences at all levels of pre-university education.
