Geostorm
Geostorm is a 2017 American science fiction disaster film about satellites that control the weather, directed by Dean Devlin and starring Gerard Butler, Ed Harris, and Andy Garcia.
Geostrophic current
A geostrophic current is an ocean current in which the Coriolis force from Earth's rotation balances the horizontal pressure gradient force, so the water flows along lines of constant pressure.
Geostrophic flow
Geostrophic flow is air or water motion in which the pressure-gradient force and Coriolis force balance, so flow moves parallel to isobars rather than across them.
Geosynchronous orbit
A geosynchronous orbit (GEO) is an Earth orbit with a period of one sidereal day, at about 35,786 km altitude, so satellites stay over a fixed longitude.
Geothermal gradient
The geothermal gradient, also called the geothermic gradient, is the rate at which temperature rises with depth in the Earth, averaging about 25–30 °C per kilometer near the surface.
Geothermobarometry
Geothermobarometry is the quantitative estimation of the temperature and pressure at which an igneous or metamorphic rock reached chemical equilibrium, calculated from mineral compositions and reaction thermodynamics, typically giving peak metamorphic conditions.
GEOTRACES
GEOTRACES is an international scientific program studying the distribution of trace elements and their isotopes in the ocean, with its main field effort launched in 2010.
