Earth Science

Earth sciences, the fields of study concerned with the solid Earth, its waters, and therefore the air that envelops it. Included are the geologic, hydrologic, and atmospheric sciences. The broad aim of the world sciences is to know these features and therefore the past evolution of Earth and to use this data, where appropriate, for the advantage of humankind. Thus, the essential concerns of the world scientist are to watch, describe, and classify all the features of the world, whether characteristic or not, to get hypotheses with which to explain their presence and their development, and to plan means of checking opposing ideas for his or her relative validity. In this way the foremost plausible, acceptable, and long-lasting ideas are developed.
