Earth Science is the study of the materials that make up the Earth and the natural and human processes that shape the landscape. During the course of your studies, much of your learning will occur in class, field study and during labs. You ll work across four disciplines of geology, geophysics, geography and archaeology to develop your understanding of how natural systems affect human culture and are influenced by it. Earth Scientists have global career opportunities in areas such as the oil and gas industry, international development, natural resources development, research and more.
