Teaching methods and learning activities

Presentation and discussion of the foreseen contents. Its practical application on the characterization and classification of the sedimentary rocks. As didactic resource will be used Powerpoint presentation which will be put on-line (http://elearning.fc.up.pt/aulasweb/) for the students use.

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

The students have to attend at least 2/3 of the sessions.

Calculation formula of final grade

Final evaluation (60%) and practical exam (40%).
