Earth Science is the scientific study of the planet Earth, its physical constitution, structure, processes, and the dynamic interactions among its four major systems: the geosphere (solid Earth), hydrosphere (water), atmosphere (air), and biosphere (life). It is an interdisciplinary field that seeks to understand Earth's past, present, and future through the application of physics, chemistry, biology, and mathematics to planetary-scale phenomena. Its scope encompasses a vast range of subjects from the deep interior of the planet to its surrounding space environment, aiming to explain the origin, evolution, and ongoing changes of Earth's features and systems.
