Geology is a broad scientific discipline that studies the Earth, its materials, landforms, processes and history. It branches into many aspects of the physical planet, such as earthquakes, volcanoes, mudslides and flooding. Exploration geologists use their knowledge of the Earth's surface to discover resources of value. Geology is a science that aims to understand all aspects of our planet, ranging from the Earth's surface to the deep interior. It also aims to discover how the Earth has evolved during the past 4.4 billion years, including the origin of continents, oceans, atmosphere and life. Applying knowledge of Earth processes and time scales is fundamental to locating resources such as groundwater, petroleum and minerals, and understanding climate and other environmental changes. Most of Australia's mineral and petroleum resources are in Western Australia, so UWA is well placed for students to gain geological skills. Teaching methods consist of lectures from leading experts and industry professionals, practical, computer and laboratory classes and tutorials. This major also includes extensive field work and four field trips of three to ten days.
