L10. The geomagnetic field; The magnetic field of a dipole; Multipole and spherical harmonic representation of the geomagnetic field
L11. Introduction to hydromagnetic dynamos
L12. Geomagnetic instrumentation and design
L13. Solar-terrestrial interactions of the geomagnetic field
L14. Telluric currents and the conductivity structure of the Earth.
L15. EM methods of prospecting

||Written Exam: 70%, Course Work: 30 %, Practical Exam: 0%.
The exam consists of a single 3hr written paper in April/May.
Past exam papers: https://exampapers.ed.ac.uk/search/Physics+of+the+Earth
The coursework consists of three reports based on 3 of the Practicals (see below), each contributing 10% to the overall mark. The reports should not exceed 1500 words.
If you want to attain the best marks it is worth looking at the Common Marking scheme to understand how you will be assessed.
There are three practical assessments that 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 except for the third assessment on 20th March which is to be submitted in hard copy ¿ please see details below and on the Learn submission page. The hardcopy assessment is to be submitted into the Teaching Office, Room 332 in the Grant Institute by 12noon on the deadline day. Any electronic or hardcopy 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 and your Personal Tutor know before the hand-in date.
Practical Hand In Deadlines:
P1 ¿ Week 3, Tuesday 30 January 2018, 12noon (FORMATIVE) via Turnitin submission box on Learn
P2 ¿ Week 6, Tuesday 27 February 2018, 12noon (ASSESSED) via Turnitin submission box on Learn
P3 ¿ Week 9, Tuesday 20 March 2018, 12noon (ASSESSED) hard copy submission via Rm 332 Grant Institute

Assessment and Feedback information
For information regarding the School of Geosciences policy for Special Circumstances please see:
All details related to extensions procedures and late penalties can be found in the
School of GeoSciences General Information Handbook 2017-18
||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.
In the first week there is a formative Practical, which will be marked and the results returned to you prior to the hand-in of the second assessment which contributes to your mark. You will have the opportunity to get individual feedback on the first report in a meeting with the CO, Mark Naylor.
Further subject specific questions can be directed towards the relevant lecturers and/or the demonstrators.
||Hours & Minutes
|Main Exam Diet S2 (April/May)||3:00|
|Resit Exam Diet (August)||3:00|
| 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.
