Objectives

On completion of this module, students should be able to:

i) Derive, understand and apply the key equations that govern the transport of heat in the earth system, specifically those that control the depth of the seafloor.
ii) Understand how satellite geodetic systems (InSAR and GNSS) work, critically assess their limitations, and use the data to solve problems in plate tectonics and continental deformation.
iii) Understand the different mechanisms that control how the earth deforms during the earthquake cycle and use observations of this deformation to derive properties of the earth system.
iv) Understand the physical processes that result in glacial isostatic adjustment and flexure of the lithosphere, and use simple equations governing these processes to derive Earth properties.
v) Understand what controls the distribution of seismic hazard in the continents.
vi) Write simple codes that model physical processes, including heat flow, plate motion, elastic dislocations and viscoelastic earthquake cycles.
vii) Critically compare model predictions to real geophysical data.
viii) Produce write-ups of lab-based modelling activities in the form of a short scientific paper, including a critical comparision of the results of the lab with key results from the academic literature.
ix) Understand how Optical Remote Sensing works, and how it can be used for studying geology and tectonic processes remotely.

Learning outcomes
The aim of this module is to allow students , to understand the mechanisms governing the dynamics of tectonic plates and how the continents deform, and a variety of related geophysical phenomena and interpret related observations in terms of the fundamental underlying physics of the system.

Opportunities for Formative Feedback

The laboratory sessions allow student progress to be monitored by in class monitoring. Detailed formative assessment and feedback will be given on one lab, and formal summative assessment of one lab report will take place. In addition, two problem sets will be given and the solutions discussed in problem classes.
