Geomorphological mapping
Geomorphological mapping is a cartographic method that divides terrain into units defined by landform shape, formative process, surface material, and age, used in hazard assessment and land planning.
Geomorphology
Geomorphology is the study of Earth's landforms and the processes that shaped them, from continents and river basins to beaches and glaciers, now also applied to Mars and Titan.
Geomunoreum Lava Tube System (거문오름)
Geomunoreum Lava Tube System (거문오름 용암동굴계), a network of about 20 lava tubes on Jeju Island, South Korea, formed by pahoehoe flows from the Geomunoreum scoria cone; part of the 2007 UNESCO Jeju Volcanic Island and Lava Tubes World Heritage site, with 7,416 m Manjanggul and rare carbonate speleothems.
Geomys
Geomys is a genus of fossorial rodents in the family Geomyidae, called eastern pocket gophers, distinguished by two deep grooves on each upper incisor and living in the southeastern United States and northern Mexico.
Geon‐Tae Park
Geon-Tae Park (박건태) is a South Korean materials researcher working on cathode materials for lithium-ion batteries, with a 2023 Ph.D. from Hanyang University and a visiting post at the University of Washington.
GeoNames
GeoNames is a free geographical database, or gazetteer, with over 32 million placenames worldwide, REST web services, and wiki-style community editing under a Creative Commons license.
Geonim (גאונים)
The Geonim (גאונים) were heads of the Babylonian academies of Sura and Pumbedita, regarded as the leading Jewish religious authorities from 589 to 1038 CE.
GeoPackage
GeoPackage is an open format defined by the Open Geospatial Consortium for storing vector features, raster tile pyramids, and attributes in a single portable SQLite database, first published in 2014.
GeoPark
GeoPark is an independent oil and gas company headquartered in Bogotá, Colombia, founded in 2002 and traded on the New York Stock Exchange as GPRK.
GeoParquet
GeoParquet is an OGC-backed specification for storing geospatial vector data (points, lines, polygons) in Apache Parquet. Version 2.0.0 uses native Parquet GEOMETRY/GEOGRAPHY types, WKB encoding, and a JSON geo metadata key with PROJJSON CRS.
Geophagia
Geophagia (geophagy), deliberate eating of earth, soil, or clay, a form of pica; documented since Hippocrates, most common in pregnant women and children, best explained as protection from pathogens and toxins, with risks of anemia, obstruction, and heavy metal exposure.
Geophone
A geophone is a seismic sensor converting ground motion into an electrical signal via a spring-suspended coil in a magnetic field, standard in onshore seismic exploration.
Geophysical Fluid Dynamics Laboratory
The Geophysical Fluid Dynamics Laboratory (GFDL) is a NOAA federal research laboratory on Princeton University's campus in Princeton, New Jersey, a leader in climate modeling since 1955.
Geophysical imaging
Geophysical imaging is a family of earth-science methods that reconstructs models of subsurface structures and properties such as seismic velocity, resistivity, and density from field measurements.
Geophysical survey
A geophysical survey maps buried features and geological structure by remotely measuring physical properties of the subsurface, with magnetometry, resistivity tomography, and ground-penetrating radar the most used techniques.
Geophysics
Geophysics, also called Earth physics, is the natural science applying physics to Earth's structure and dynamics, using gravity, magnetic, electrical, and seismic measurements to infer subsurface properties.
Geopolitical zones of Nigeria
The geopolitical zones of Nigeria are six informal groupings of the country's 36 states and the FCT, dating from the mid-1990s and used to allocate political posts and funds.
Geopolitics
Geopolitics, from German Geopolitik coined by Rudolf Kjellén in 1899, studies how geography shapes power in international relations; classical thinkers include Mackinder, Mahan, and Spykman, later challenged by critical geopolitics.
Geopolitics (journal)
Geopolitics is a peer-reviewed Taylor & Francis journal founded in 1996 by Richard Schofield as Geopolitics and International Boundaries. It publishes multidisciplinary research on geopolitics and political geography, with a 2025 impact factor of 3.8 (Q1).
Geopolymer cement
Geopolymer cement is a binder made by alkali activation of aluminosilicate materials such as metakaolin, fly ash, or slag, forming inorganic polymer networks with lower carbon emissions than Portland cement.
Geopolymer concrete
Geopolymer concrete (GPC, also called geocrete) is concrete whose binder comes from alkali-activated fly ash, slag, or metakaolin, cutting CO2 emissions by up to 70%.
Geopotential height
Geopotential height is an altitude measure used in meteorology that expresses height by potential energy against gravity rather than geometric distance, differing slightly from true height.
Geopotential model
A geopotential model is a mathematical representation of Earth's gravitational potential, delivered as spherical harmonic coefficients from which geoid undulations, gravity anomalies, and satellite orbits are computed.
Geopressured geothermal energy
Geopressured geothermal energy is heat, hydraulic pressure, and dissolved methane recovered together from deeply buried, overpressured sedimentary formations, studied mainly in the US Gulf Coast.
GeoPura
GeoPura is a British green-hydrogen power company, founded in 2019 and based in Newcastle upon Tyne, that leases hydrogen fuel cell power units replacing diesel generators.
Geordi La Forge
Geordi La Forge is the blind Starfleet chief engineer of the USS Enterprise-D in Star Trek: The Next Generation, played by LeVar Burton, who sees through the VISOR device later replaced by ocular implants.
Geordie
Geordie is the dialect and accent of Tyneside, Newcastle upon Tyne, England, also called Tyneside English, developed from Northumbrian Old English, first written in the late 18th century, known for conservative vowels like "hoose" and strong local identity.
Geordie (band)
Geordie were a Newcastle upon Tyne glam and hard rock band formed in 1972, known for UK hits "All Because Of You" (No. 6, 1973) and as Brian Johnson's band before he joined AC/DC in 1980.
Geordie Greep
Geordie Greep (born 1999), also known as MC Spritz, is an English musician, former frontman of experimental rock band black midi (Schlagenheim, Hellfire) and solo artist behind The New Sound (2024). In October 2026 he denied sexual assault allegations made in Vancouver and cancelled US tour dates.
