Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

Geology – one of the Earth sciences – is the study of the Earth, with the general exclusion of present-day life, flow within the ocean, and the atmosphere. The field of geology encompasses the composition, structure, physical properties, and history of Earth's components, and the processes by which it is shaped.
In 1741 the best-known institution in the field of natural history, the National Museum of Natural History in France, created the first teaching position designated specifically for geology. [19] This was an important step in further promoting knowledge of geology as a science and in recognizing the value of widely disseminating such knowledge.
The first life arose from abiotic chemical reactions. When this happened, how it happened, and even what planet it happened on are uncertain. However, life follows the rules of and arose from lifeless chemistry and physics. It is constrained by principles such as thermodynamics. This is an important concept in the field because it represents ...
Early works discussing Earth system science, like these NASA reports, generally emphasized the increasing human impacts on the Earth system as a primary driver for the need of greater integration among the life and geo-sciences, making the origins of Earth system science parallel to the beginnings of global change studies and programs.
Also known as Earth science education, It is the study of Earth's physical features, processes, and systems, as well as the natural and human-induced events that shape it. It encompasses a wide range of disciplines, including geology, oceanography, meteorology, climatology, environmental science, and more.
By acquiring these series, GSA aims to elevate and expand its reach in innovative and accessible ways. For example, the Roadside Geology series turns ordinary road trips into educational adventures, showcasing geology’s relevance to everyday life. This acquisition will enable GSA to foster a deeper public appreciation of Earth’s geoheritage ...
This includes all its fossil content and the information it yields about the history of the Earth: its past climate, geography, geology and the evolution of life on its surface. According to the law of superposition , sedimentary and volcanic rock layers are deposited on top of each other.
