| Course description |
Syllabus
1. The one-dimensional Earth and Earth materials ¿ reference Earth models and the data that go into them, composition of the mantle and core, composition changes as a function of depth, hydrostatic equilibrium and the effect of compression, the Adams-Williamson equation, ways of determining properties of materials at high temperature and pressure.
2. The crust-mantle system ¿ melting of rocks and chemical differentiation, radiometric dating and isotopic evolution.
3. Gravity and the geoid.
4. Mantle rheology and convection-types of deformation and mechanisms of creep, timescales on which they operate, observational information, Rayleigh number for the mantle, Newtonian and non-Newtonian mantle convection and plate tectonics.
5. The three-dimensional Earth ¿ mantle seismic tomography and its interpretation.
6. Core convection, structure and dynamics ¿ essential force balance, Navier-Stokes equation, essentials of the geodynamo including its energy source, waves in the core, inner core (including anisotropy, super-rotation).
7. The D" region ¿ structure, composition (including post-Perovskite, anisotropy), core-mantle coupling, influence on the geodynamo.
8. Cosmology, celestial mechanics, and the search for extrasolar planets.
9. Sending rockets, satellites and people to other planets.
10. Meteorites and their composition and origin.
11. Comparative Planetology ¿ surfaces, energy budgets, geophysical properties, and atmospheres.

Written Exam: 70%, Course Work: 30%, Practical Exam: 0%.
To pass you need to obtain an average of 40% or greater for the course - you do not need to pass both components.
The course work consists of 3 parts: (1) a computer-based practical to infer density within the Earth (10%), (2) an individual 5- min presentation on written on a topic related to Planetary Colonization (10%) and (3) a group presentation on a key topic in Planetary Interiors (10%).
Assessment deadlines
5 minute presentations (formative) Same day - Friday, Week 9, S1
Computer-based density practical - Monday, Week 11, S1
5 minute presentations (summative) - Friday, Week 10, S1
Group presentations (formative) - Friday, Week 4, S2
Group presentations (summative) - Monday, Week 10, S2

| Feedback |
Feedback will be given via written comments on class assessments as well as through in-class discussions. A formative assessment of group presentations will be given a week prior to the summative assessment. There will also be also be opportunities for feedback via in-class discussions on tutorial classes in the second semester. |

Learning Outcomes
On completion of this course, the student will be able to:
- Interpret global geophysical information in terms of simple models of planetary interiors
- Understand heat flow through the Earth's surface; understand the possible forms of convection in the mantle and core, and the constraints on fluid motion from geophysical observations
- Understand and evaluate the different methods used to search for exoplanets; deduce chemical and physical properties for other planets by comparison with those of the Earth
- Understand the three-dimensional structure of the Earth and how it is determined, using both highly mathematical and physical understanding and approaches
- Review critically and consolidate knowledge in the relevant areas, and offer professional level insights into the subject

Additional Information
| Graduate Attributes and Skills |
Students will gain specialist knowledge in global scale geophysics. The course will require the student to be independent critical thinkers evidenced through the evaluation of different approximations and opposing models of the physical structure and properties of the Earth and other planets. We the students will expect to be resourceful and independent learners in gathering supporting material throughout the course, and reflective in integrating knowledge and skills gathered both in this and prerequisite courses. |
