Volcanoes, earthquakes, mountain chains and the diversity of the Earth's rocks tell us that the Earth has been a dynamic planet since its formation 4.6 billion years ago. This course has two main aims: to impart an understanding of the processes which shape the Earth, and to develop practical skills in recognising the evidence of these processes in rocks, both in the field and in the laboratory. The course will have a primary focus on the materials of which the Earth is made, how the major constituents are distributed between core, mantle and crust and how this changes with time through the agencies of plate tectonics and volcanism. Geological resources, from energy, to minerals, and water, are essential for all aspects of society. How these resources are categorised, and where they are they formed is part of our fundamental understanding of the Earth as an integrated system.
