This module builds on students’ current knowledge to develop a deeper understanding of the Earth's internal structure and dynamics, and interactions between surface and deep processes. Evidence from a variety of geophysical techniques is evaluated, including the rapidly developing field of seismic tomography, which produces fuzzy images of thermal and compositional anomalies such as mantle plumes and subducted lithospheric plates. Students will read a variety of journal articles as a basis for discussion of current theories and controversies about how the Earth works.
By completing this module, students will demonstrate a good understanding of the principles behind, and applications of, a variety of geophysical techniques in addition to an enhanced ability to compare, contrast and synthesise different types of evidence about how the Earth works. Students will also gain the necessary level of knowledge to be able to discuss and distinguish current theories and debates, such as the mantle plume controversy, and will learn to apply stereonets to determine earthquake focal mechanisms.
