Physics of Earth's Interior
A.Y. 2024/2025
Learning objectives
The course aims to deepen the knowledge of the physical mechanisms that regulate the dynamics of the deformation processes involving the crust-mantle system at small and large-scales, both spatial and temporal.
Expected learning outcomes
Capability to understand the physical laws that govern the processes that take place at different scales on our Planet.
Capability to solve a complex problem using appropriate mathematical tools.

Prerequisites for admission
Good knowledge of the basic concepts of continuum mechanics.
Teaching methods
The lessons will take place in the classroom using the classic chalk blackboard and, only occasionally, by projecting powerpoints.
Teaching Resources
A pdf file, which contains an exhaustive presentation of the topics covered in class and which can be used as a text for the study, will be made available on the didactic web page accessible through the ARIEL portal.
Texts for further information:
G. Ranalli, Rheology of the Earth, Deformations and flow processes in geophysics and geodynamics.
D. Turcotte and G. Schubert, Geodynamics, Application of continuum physics to geological problems.
Several copies of both texts are available in the library of the Department of Earth Sciences "A. Desio".

Assessment methods and Criteria
The exam will take place in written form and will be aimed at verifying the student's knowledge of the physical mechanisms that regulate the dynamics of the deformation processes involving the crust-mantle system on different scales, both spatial and temporal.
The test lasts 2 hours and consists of three questions of different evaluation weight. The first question (maximum 15 points), open-ended, involves the discussion of a theoretical topic. The second question (maximum 10 points), with an open answer, involves the reproduction of one of the exercises solved during the practical lessons and the discussion of its implications. The third question (maximum 5 points), multiple choice, foresees, for 5 different questions, the selection of a single answer in a list of three and aims at verifying the knowledge of the orders of magnitude of the physical quantities used.
