Exam Details: In Person Exam
The exam consists of a single 3hr written paper in May.
The coursework consists of three reports based the 3 Practicals (see below), each contributing 10% to the overall mark. The reports should not exceed 1500 words, excluding figures, figure captions and references. These three practical assessments must be handed in during Semester 2 with a report describing the aims, background, method, results and conclusions from each practical exercise.
These assessments will be submitted electronically on the Learn submission page. Any assessment handed in without a satisfactory explanation after the due date will be subject to an automatic penalty, so if you are aware of a problem, please do let the Course Organiser, the Course Administrator, and your Student Advisor.
If you want to attain the best marks it is worth looking at the Common Marking scheme to understand how you will be assessed. Allowing for differences in ability, there is a strong correlation between engagement with lectures and tutorials and the final mark. Tutorials are an integral part of the course, and lecturers will assume you have done these in preparing for then exam. Attendance at practicals is compulsory unless an exemption has been given in advance or exceptional circumstances occur near the time of the scheduled practical
All details related to extensions procedures and late penalties can be found in the https://www.ed.ac.uk/staff/supporting-students/academic-procedures/coursework-extensions.
P1 Week 5, Thursday, 12noon (ASSESSED) via Turnitin submission box on Learn
P2 Week 8, Thursday, 12noon (ASSESSED) via Turnitin submission box on Learn
P3 Vacation 2 Week 1, Thursday, 12noon (ASSESSED) via Turnitin submission box on Learn
Students must attain an overall mark of 40% (or above) to pass the course. |
| Feedback |
The tutorials are an opportunity to get feedback on exam relevant questions. You will get the most out of these by attempting the questions in advance. They are available on learn.
Further subject specific questions can be directed towards the relevant lecturers and/or the tutor/demonstrators.

Learning Outcomes
On completion of this course, the student will be able to:
- 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.
- Have the ability to solve analytical mathematical problems for determining the structure and behaviour of the Earth.
- Have gained practical experience and understanding of geophysical techniques and how observations can be interpreted
- Have experience in the practical sessions of carrying out scientific lines of enquiry into professional level problems.
- Gain experience in critically evaluating evidence-based solutions to these problems and in in conveying complex information to a range of audiences for a range of purposes in writing the practical reports - a valuable transferable skill
