For the purposes of considering applications for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005) and Students Experiencing Academic Disadvantage Policy, this subject requires all students to actively and safely participate in laboratory activities. Students who feel their disability may impact upon their participation are encouraged to discuss this with the Subject Coordinator and the Disability Liaison Unit.

This subject provides an overview of the processes controlling the formation and evolution of our global environment. We begin by exploring the origin of the Earth as a planet within the solar system, its layered structure and (solid and fluid) constituent properties, and the importance of the orbital characteristics in controlling changes in the global climate. The evolution of the major physical features and landscapes of the Earth, including the continents, ocean basins and mountain belts, are described in terms of plate tectonics and its constituent processes of continental drift and sea-floor spreading. The nature of volcanic and earthquake processes, that are concentrated at plate boundaries, and also those that occur more widely, like weathering and erosion, transport of sediments and biogeochemical cycling are also discussed. The evolution and origin of life on Earth are discussed in the context of evolving atmospheres and climates. The structure and general circulation of the atmosphere and ocean are also examined, including descriptions of the Earth’s present climate, the hydrological cycle, weather systems, ocean currents, and past and future climate change. Throughout the course, the material will highlight the potential societal benefits, e.g., mineral resources and alternative energy sources, as well as natural hazards like volcanoes, earthquakes, severe weather, and future climate change.
On completion of this subject, students should have gained a holistic view of the global environment, encompassing the solid and fluid Earth and its formation, evolution, and modern structure. Students will be familiar with: the materials that comprise the Earth, atmosphere and oceans; the complex interplays between these three media; the modes of formation and the underlying processes that drive the evolution of the solid Earth and landscape; and changes in the Earth’s climate on modern and geological timescales. This subject provides the foundation for further study in Geology and/or Atmospheric and Oceanic sciences.
Short tests held during practical sessions (20%); a group research project with an in-class poster presentation (15%); a Weather Diary group assessment task (15%); a 2-hour written examination in the examination period (50%). A reading topic will be assessed in the examination.
