Geology

Geology is the scientific study of the Earth, specifically its solid materials, internal and surface structures, and the processes that have shaped and continue to shape the planet over time.  It is a discipline within earth science and focuses on understanding rocks, minerals, landforms, and the physical dynamics operating within the Earth’s interior and on its surface.  Geologists investigate how materials such as igneous, sedimentary, and metamorphic rocks form and transform through processes like melting, crystallization, erosion, deposition, and metamorphism, all of which are governed by physical and chemical principles.

Geology has practical applications in areas such as natural resource exploration (including minerals, hydrocarbons, and groundwater), environmental assessment, and natural hazard analysis.  These applications are grounded in established methods such as field mapping, laboratory analysis, and geophysical surveying.  The meaning and scope of geology as described here are well-documented and supported by extensive empirical evidence across multiple subfields.
