1st Cycle Studies

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.

1. Introduction. Physics of the Earth. Field theory. Introduction to fractal geometry.

2. Gravity. Geodesy and gravity field. Newton's laws. Gauss theorem. Laplace and Poisson equations. The geoid. Expansion of the gravitic potential. Satellites. Tides. Gravimetry: gravimeters, corrections, Bouguer anomaly, Bouguer density. Isostasy. Gravity in the Solar System.

3. Geomagnetism. Maxwell's laws. Field components. Main field. Expansion of the magnetic potential. Introduction to the study of nonlinear dynamic processes: chaos. Models of the main field. External field. Magnetometry. Local fields. Hysteresis and rock magnetism. Magnetism in the Solar System.

4. Seismology. Stress and strain. Elasticity: Hooke's law. Wave equation. Body waves: Huygens' and Snell's laws; Zöppritz equations. Surface waves. Seismometry. Magnitudes. Seismicity. Models. Intensity. Seismic prevention and prediction. Seismology in the Solar System.
