4 Teaching methods

Lectures and ecercises
5 Prerequisites (for the module)

Formal: None.
The content of the course requires the undergraduate knowledge of mathematics, physics and applied geophysics.
6 Type of examination

At the beginning of the lecture-free period, there is a 120 to 180-minute written examination, the content of which is the material from the lecture and exercises. Successful completion of the exercises is required for admission to the examination; for this, the acquisition of 50% of the points to be achieved is sufficient. A repeat examination is offered before or at the beginning of the following semester. The examination grade is the module grade. In the case of two passed examinations (see § 20 paragraph 10 examination regulations), the better grade is the module grade.
7 Credits awarded

The module is passed, and the credit points will be awarded, if the written examination is passed.
8 Compatibility with other curricula

Suitable as an elective course for physics students.
9 Proportion of final grade

Weight of the module grade in the overall grade: 6/150 (4 %)
