Earth Science研究地球物理环境的功能，发展和使用，并涉及其大气和海洋，其表面过程以及地壳和内部的研究。它还涉及对地球自然资源和自然资源的研究，并纳入了地理，地质，地球物理学，海洋学和生物科学等传统学科的交叉学科。
Earth Science investigates the functioning, development and use of 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 Earth's natural and physical resources, and incorporates interdisciplinary subjects across the traditional disciplines of geography, geology, geophysics, oceanography and biological sciences. The course focuses on applying knowledge of these disciplines to understanding and solving problems. The subject's growth has been in response to changing demands in industry and the practical needs of interdisciplinary scientific research, together with the needs arising from an increased community awareness of the Earth, its environment stresses and patterns of change.
