The course is an introduction to physics of the solid Earth intended for students with substantial background in physics and mathematics including calculus. The course will provide an overview of the structure and evolution of the Earth as a dynamic planet within our solar system. Physical principles will be applied to the following topics: theory of elasticity and elastic wave propagation; modern global seismology as a probe of the Earth's internal structure; earthquakes and the description of seismic sources; a simple but fundamental theory of thermal convection; the distinctive rheological behaviour of the upper mantle and its top layer, controlled by significant changes in the mechanical properties of the material, will then be explored to arrive at a comprehensive description of what forces drive and resist global plate motions.

Honours Pathway Option

Students taking the HP advanced option will undertake an individual project on a topic of interest from the course syllabus. Such project shall develop in consultation with the course lecturers, and may be in the form of a reading project or a laboratory/numerical experiment accompanied by a final report. The assessment of the project will be agreed upon and undertaken in a manner appropriate to the project itself (e.g. a written report or essay, a short talk etc.). Students taking the HP option may elect to substitute their project mark either with up to two (out of four) individual assignments or with one of the experiments and accompanying report normally undertaken during the course (this amounts to a total of 10-20% of the final grade). The assessment weight towards the exam will remain the same.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Discuss the theoretical basis for modern global seismology and employ methods based on such theory to understand earthquake phenomena and the seismological probing of earth structure.
2. Explain the governing dynamics of mantle and lithosphere, and use such understanding to make reliable estimates of the forces controlling plate motions and their temporal changes.

Research-Led Teaching

In both modules, the lectures consist of fundamental Earth physics concepts, as well as selected groundbreaking research results of the past few years. Usually, this is a selection of results developed by the Seismology & Mathematical Geophysics group at ANU, and/or other significant recent results within the intellectual context of the course. A significant element of research-led teaching occurs through students' oral presentations of the selected research papers where we engage in group discussions and explore how the selected papers utilize and address topics from the course curriculum. In module 2, the computer labs are based on research codes that can be applied to relatively simple problems that we encounter in the course. This course has been adjusted for remote participation in Sem 2 2021, however, students are encouraged to attend on-campus activities if possible. The lectures will be recorded. The labs will be delivered in a dual-mode: online participants will require convenient and stable access to the Unix/Linux server. We strongly recommend students attend on-campus labs.

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the Academic Integrity . In rare cases where online submission using Turnitin software is not technically possible; or where not using Turnitin software has been justified by the Course Convener and approved by the Associate Dean (Education) on the basis of the teaching model being employed; students shall submit assessment online via ‘Wattle’ outside of Turnitin, or failing that in hard copy, or through a combination of submission methods as approved by the Associate Dean (Education). The submission method is detailed below.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.

Academic Integrity

Academic integrity is a core part of the ANU culture as a community of scholars. At its heart, academic integrity is about behaving ethically, committing to honest and responsible scholarly practice and upholding these values with respect and fairness.

The ANU commits to assisting all members of our community to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. The ANU expects staff and students to be familiar with the academic integrity principle and Academic Misconduct Rule, uphold high standards of academic integrity and act ethically and honestly, to ensure the quality and value of the qualification that you will graduate with.

The Academic Misconduct Rule is in place to promote academic integrity and manage academic misconduct. Very minor breaches of the academic integrity principle may result in a reduction of marks of up to 10% of the total marks available for the assessment. The ANU offers a number of online and in person services to assist students with their assignments, examinations, and other learning activities. Visit the Academic Skills website for more information about academic integrity, your responsibilities and for assistance with your assignments, writing skills and study.

Online Submission

You will be required to electronically sign a declaration as part of the submission of your assignment. Please keep a copy of the assignment for your records. Unless an exemption has been approved by the Associate Dean (Education) submission must be through Turnitin.

Hardcopy Submission

For some forms of assessment (hand written assignments, art works, laboratory notes, etc.) hard copy submission is appropriate when approved by the Associate Dean (Education). Hard copy submissions must utilise the Assignment Cover Sheet. Please keep a copy of tasks completed for your records.

Late Submission

Individual assessment tasks may or may not allow for late submission. Policy regarding late submission is detailed below:

• Late submission permitted. Late submission of assessment tasks without an extension are penalised at the rate of 5% of the possible marks available per working day or part thereof. Late submission of assessment tasks is not accepted after 10 working days after the due date, or on or after the date specified in the course outline for the return of the assessment item. Late submission is not accepted for take-home examinations.

Referencing Requirements

Accepted academic practice for referencing sources that you use in presentations can be found via the links on the Wattle site, under the file named “ANU and College Policies, Program Information, Student Support Services and Assessment”. Alternatively, you can seek help through the Students Learning Development website.

Returning Assignments

Assignments will be returned via different mechanisms. Check with the course and module conveners.

Extensions and Penalties

Extensions and late submission of assessment pieces are covered by the Student Assessment (Coursework) Policy and Procedure. Extensions may be granted for assessment pieces that are not examinations or take-home examinations. If you need an extension, you must request an extension in writing on or before the due date. If you have documented and appropriate medical evidence that demonstrates you were not able to request an extension on or before the due date, you may be able to request it after the due date.

Resubmission of Assignments

Not permitted
