This course investigates the entire earth system, from core to crust, through geological time and from a range of scales. Students learn about the origins of the Earth and the broad-scale tectonic forces that underpin the formation and destruction of continents. They investigate the composition of the crust from both mineralogical and resource-potential perspectives and examine the processes that modify and sculpt the surface of our planet. Students study the evolution of life and the interaction between the biosphere and earth, including the impact of geology on human civilisation. This is carried with a specific focus on current geohazards and the future challenges facing our planet.
