Summary of Intended Learning Outcomes
| At the end of this course, you should have a broad, comprehensive overview of the physical processes operating in the solid Earth and its core and a quantitative understanding of the principles of the geophysical techniques by which this information is derived. You will also have gained practical experience and understanding of geophysical exploration techniques and how observations can be interpreted. These practical sessions will give you experience of carrying out routine lines of enquiry into professional level problems. You will be able to critically evaluate evidence based solutions to these problems. The assessed scientific report and degree exams will give you practise conveying complex information to a range of audiences for a range of purposes which is a valuable transferable skill. |
Assessment Information
1 written exam in the diet, scheduled for the end of the year (70%).
Assessment of practical reports (30%). |
