Fisica (9 CFU) preparatory class.

Main aim of the course is a basic knowledge about the main physical properties of solid earth and the role of
physical phenomena in the whole body of planet.

Main topics. The role of elasticity of rocks in source mechanisms and in propagation of seismic waves,
geometry of seismic waves travels in the whole body oh earth; location of epicenters and determination of
focuses depth. The role of terrestrial gravity and pression in defining the model for mantel, outer and inner core
of the earth; the measurement of gravity; the International Gravity Formula and gravity anomalies; gravimeters
and measurements, gravity anomalies and structures in the crust. Magnetic field of the earth expressed as an
effect of a central dipole: the outer (liquid) core as the cause of main field; time variations of the terrestrial
magnetism; magnetic properties of rocks and magnetic anomalies; main types of magnetometers.

The class compounds mainly of lectures.
