Earth Sciences is the most multidisciplinary of the Natural Sciences. Our understanding of the Earth and other planets is based on research across the whole spectrum of the Earth Sciences and includes the areas of Geophysics, Geochemistry, Mineral Sciences, Petrology, Palaeontology, Vulcanism, Marine Sciences, Palaeoceanography. We focus on particular aspects of the earth; its internal structure and evolution, the behaviour and properties of minerals as natural materials, oil, gas and other natural resources, Earth history as recorded in rocks and fossils, the origin of life and global climate change. We draw on the expertise of the neighbouring sciences, mathematics, chemistry, physics, material sciences, geography and the biological sciences.
