Geology is the study of Earth -- the materials that make it up, the processes that act on those materials, and the history of the planet and its life forms. The rocks under a specific area have a significant impact on how that land can best be used.
Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It includes the study of organisms that have inhabited our planet.
Geology - Study of the structure of the Earth: The scientific objective of geodesy is to determine the size and shape of the Earth. The practical role of geodesy is to provide a network of accurately surveyed points on the Earth's surface, the vertical elevations and geographic positions of which are precisely known and, in turn, may be incorporated in maps.
