Acquisition of scientific skills and basic techniques for the study of the seabed, the relationship between tectonics and sedimentation and the zonal and ubiquitous characters of the main depositional processes.
Knowledge and understanding: The student must demonstrate knowledge and understanding, at a basic level, the problems related to the main geological processes concerning marine geology, sedimentology, geodynamics of continental margins and oceanic areas and the main geophysical techniques of data acquisition.
Ability to apply knowledge and understanding: The student must demonstrate the ability to use the basic concepts acquired for the definition of the different coastal stratigraphic and tectonic contexts.
Autonomy of judgment: The student must be able to recognize autonomously the different marine environments and the geological processes that characterize them.
Communication skills: The student must have the ability to recognize and describe the different themes of the course correctly using scientific language.
Learning skills: The student must be able to continuously update himself, through the consultation of texts and publications (also in English) in order to acquire the ability to deepen the topics of the Marine Geology sector.

The objective of the exam consists in verifying the level of achievement of the previously indicated training objectives.
The exam consists of an oral test in which the ability to describe link and compare different aspects treated during the course will be evaluated.
