Synopsis

This unit covers the planetary scale structure and dynamics of the Earth, and the fundamental processes which create 'geology' as a natural consequence of Earth evolution. The unit will provide an understanding of the subtle interplay between Earth structure, planetary cooling, geomagnetism, mantle convection, plate tectonics, continental drift, heat flow, earthquakes, melt generation etc, and the diverse measurements/ models needed to gain this understanding including seismicity, seismic tomography, gravity, changing sea level, post-glacial rebound etc. It will concentrate on an integrated, quantitative, model-based approach to the geosciences.

Outcomes

On completion of this unit students will be able to:

  1. Describe how the cooling of the Earth leads to internal convection;

  1. Describe how a mobile surface and horizontal stresses arise from convective motion;

  1. Visualise plate tectonics as an emergent phenomenon;

  1. Describe the basic principles of plate tectonic reconstruction;

  1. Describe how plate tectonics influences the rotation of the Earth and can change the global climate;

  1. Identify from surface observations how the tectonic stresses are balanced in different geological settings;

  1. Interpret maps of global gravity, stress, earthquake distribution, topography / bathymetry and the underlying mantle structure through seismic tomography.

Assessment

Practicals: 20%
Assignment: 20%
Examination (3 hours): 60%

Students must pass the theory examination to achieve an overall pass grade. Students who do not pass the theory examination will receive a mark of 45% unless their aggregate mark is lower, in which case that mark will be recorded.
