The main objectives of the course are three: 1. To develop in the student the conviction of the need for a deep knowledge of Physics for the different applications necessary for understanding the Earth System.2. Give the student a specific knowledge of the physical mechanisms of the interior of the planet. 3. To make the student aware of an interdisciplinary and multidisciplinary approach and the different methods useful for the study of the Earth System

Type of delivery of the course
Traditional teaching method in mixed modality. Some lectures are given on the blackboard, as those are dedicated to the numerical part and mathematical demonstrations, some others are given with the support of the slides for the most descriptive topics. The theoretical lessons are alternated with lessons dedicated to numerical exercises in order to verify students' learning and problem-solving capabilities.Type of evaluation
The exam is conducted in an oral manner aimed at verifying the level of effective understanding of the concepts and the ability to describe both the formal aspects and the physical implications of the topics covered. The duration of the exam is approximately 45 minutes. In the first part of the exam the committee asks the student to deal with a topic of his interest among those described in the program. In the second part of the exam, the committee verifies the completeness and methodological rigor used by the student in describing the phenomenology and the physics basic principles of the Earth System. teacher profile teaching materials

Type of delivery of the course
Traditional teaching method in mixed modality. Some lectures are given on the blackboard, as those are dedicated to the numerical part and mathematical demonstrations, some others are given with the support of the slides for the most descriptive topics. The theoretical lessons are alternated with lessons dedicated to numerical exercises in order to verify students' learning and problem-solving capabilities.Type of evaluation
The exam is conducted in an oral manner aimed at verifying the level of effective understanding of the concepts and the ability to describe both the formal aspects and the physical implications of the topics covered. The duration of the exam is approximately 45 minutes. In the first part of the exam the committee asks the student to deal with a topic of his interest among those described in the program. In the second part of the exam, the committee verifies the completeness and methodological rigor used by the student in describing the phenomenology and the physics basic principles of the Earth System. teacher profile teaching materials
