20440017 - GEOLOGY OF THE EARTH SYSTEM

The course aims to provide an overview of the planet Earth, introducing the basis for understanding the main geological aspects that characterize our planet. The course will also deal with the interactions between endogenous and exogenous processes in order to understand how these processes influence the shapes of the landscape. The course also aims to provide an understanding of the critical aspects related to the interactions between humans and Planet Earth regarding energy resources and the availability of chemical elements necessary for the energy transition and sustainable development. Moreover, the course aims to provide the tools to acquire knowledge about the Solar System and its planets, defining the planet Earth as an integrated system and highlighting its role within the Solar System.
During field excursions students will learn to understand the different aspects of Italian territory, with particular regard to its environmental value e fragility.

Attendance

Attendance at lectures, laboratory exercises, and field activities is governed by the Degree Program's Teaching Regulations, which should be consulted for any obligations, minimum required percentages, and provisions for particular categories of students.

Type of evaluation

Learning assessment is conducted through a written exam lasting a total of 4 hours. The exam is designed to assess: a) knowledge and understanding of basic and fundamental concepts of Earth Sciences; b) the ability to apply them to simple examples; c) the ability to read basic geological data and reports; d) the appropriate use of disciplinary terminology. The exam includes: 1) 20 multiple-choice, true/false, and open-ended questions on the geology topics covered in the course, including laboratory and field activities; (Exam duration: 1.5 hours) 2) 5 open-ended questions on topics related to "The Earth in Space"; (Exam duration: 1 hour) 3) an exercise in constructing and interpreting a simple geological section from a simplified geological map (Exam duration: 1.5 hours). Exemption Tests 1) At the end of the first semester, there will be an optional ongoing test on the topics of the first part of the course, consisting of 10 questions of the types indicated above (duration 1 hour). Passing this test allows students to take the final exam only for the theoretical part of the second semester, consisting of 10 questions, in addition to the 5 questions on Earth in Space. 2) At the end of the second semester, students will be required to submit all cartographic works completed during the cartography exercises. Submitting all cartographic works will exempt students from this part of the final exam. If all cartographic works are not submitted, the cartographic exercise will remain part of the final exam. Regarding the evaluation of answers, open-ended questions will be evaluated based on their scientific accuracy, relevance, essential completeness, ability to connect concepts, and clarity of language. The geology section is evaluated based on correct reading of the map and legend, geometric consistency, representation of stratigraphic and structural relationships, and graphic clarity. Final Grade The grade is expressed in thirtieths. The exemption tests are considered passed when the candidate achieves a passing grade of 18/30 and remain valid for one year. The overall grade is calculated by adding the marks obtained in the individual tests, considering a weighting of 2/3 for the written test, 1/6 for the geology section, and 1/6 for The Earth in Space. Taken together, the tests test knowledge and understanding, application, independent interpretation of simple cases, and written communication skills.

Attendance

The course provides rules on attendance in accordance with what is defined in the Teaching Regulations

Type of evaluation

Learning test takes place through a 4 hours lasting written assignment, aimed at verifying the level of effective understanding of the concepts and the students' ability to apply them in real contexts. The written test includes: 1) 30 questions (multiple answer, true or false, open answers) on the geology topics covered in the course (including those addressed during the field activity); 2) 5 open questions on the topics of "The Earth in Space" covered in the course; 3) the construction of a geological section starting from a simple geological map. For the theoretical part, at the end of the first semester there is a partial examination that includes 20 questions (multiple answer, true or false, open answers) related to the topics covered in the first part of the course. For those who have passed this test, the final written test related to the theory will concern exclusively the topics covered in the second semester and will consist of 20 questions (multiple answer, true or false, open answers).
