Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere , hydrosphere / cryosphere , atmosphere , and geosphere (or lithosphere ).
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. 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.

Geoscience education is a crucial component of understanding our planet and its complex systems. Educating young people about the diverse career opportunities and providing them with resources on geoscience is essential to sustain the industry and support the transition within the workforce. [6]
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.
Structural geology is the study of the three-dimensional distribution of rock units with respect to their deformational histories. The primary goal of structural geology is to use measurements of present-day rock geometries to uncover information about the history of deformation ( strain ) in the rocks, and ultimately, to understand the stress ...
Petroleum geology: the study of sedimentary basins applied to the search for hydrocarbons (oil exploration). Planetary geology: the study of geosciences as it relates to other celestial bodies, namely planets and their moons. This includes the subdisciplines of lunar geology, selenology, and martian geology, areology.
The following outline is provided as an overview of and topical guide to geology: . 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.
Why this theory is so significant is the interaction between the tectonic plates explains many geological formations. [8] In regards to marine geology, the movement of the plates explains seafloor spreading and mid-ocean ridge systems, subduction zones and trenches, volcanism and hydrothermal vents, and more.
