Key Points

Write to us for more information

Earth science investigates the functioning, development and use of the Earth’s physical environment and involves the study of its atmosphere and oceans, its surface processes and its crust and interior. It also involves the study of the Earth’s natural and physical resources and incorporates interdisciplinary themes from the traditional disciplines of geography, geology, geophysics, oceanography and biological sciences.

Program description

The course focuses on applying knowledge from these disciplines to understand and solve problems. The growth of the course has responded to the changing demands of industry and the practical needs of interdisciplinary scientific research, along with the needs arising from increased community awareness of the Earth, environmental stresses and patterns of change.

Earth scientists are involved in a variety of environmentally based careers that draw on their extensive laboratory and computational skills and experience.

Career options

Typical careers for Earth Science graduates include:

  • Mineral and water exploration
  • Geological
  • Geophysical and terrestrial topography
  • Geotechnical services
  • Conservation of natural resources
  • Mapping
  • Management and planning
  • Oceanography and marine sciences

Many transferable skills are also fostered through different learning approaches, including critical thinking, problem solving, report writing, oral presentations, statistical analysis, independent research and time management.
