The Discipline of Geology and Geophysics teaches about and undertakes research into our planet, earth. We investigate the earth, from its surface, through its crust and to its deep mantle using outcropping rocks, boreholes and geophysical remote sensing. From cataclysmic earthquakes and volcanic eruptions to imperceptibly slow surface weathering, we investigate the processes that have shaped our planet, its resources endowment and its environment throughout its 4.5 billion year history.
