Processes in the Earth's interior have exerted a profound influence on all aspects of the Earth's system through geological time. This module is designed to explore all aspects of those processes from the creation and destruction of tectonic plates to the structure of the Earth's interior and the distribution and dissipation of energy within it. This will include: the theory and mechanisms of plate tectonics, the heat distribution of the Earth's interior, the generation of magma and volcanism; the mechanisms behind earthquakes and distribution of seismic energy. The geological record of this activity, its evolution and impacts on the Earth will also be discussed.
