Geophysics is applied to societal needs, such as mineral resources, mitigation of natural hazards and environmental protection. [4] In exploration geophysics , geophysical survey data are used to analyze potential petroleum reservoirs and mineral deposits, locate groundwater, find archaeological relics, determine the thickness of glaciers and ...
F2 propagation (F2-skip) is the reflection of VHF signals off the F2 layer of the ionosphere. The phenomenon is rare compared to other forms of propagation (such as sporadic E propagation , or E-skip) but can reflect signals thousands of miles beyond their intended broadcast area, substantially farther than E-skip.
As defined by National Geographic, geo-literacy is "the ability to use geographic understanding and geographic reasoning to make decisions". [1] History
GEO600 is a gravitational wave detector located near Sarstedt, a town 20 kilometres (12 mi) to the south of Hanover, Germany.It is designed and operated by scientists from the Max Planck Institute for Gravitational Physics, Max Planck Institute of Quantum Optics and the Leibniz Universität Hannover, along with University of Glasgow, University of Birmingham and Cardiff University in the ...
Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth.
A geostationary orbit, also referred to as a geosynchronous equatorial orbit [a] (GEO), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km (26,199 mi) in radius from Earth's center, and following the direction of Earth's rotation.
Topics of geopolitics include relations between the interests of international political actors focused within an area, a space, or a geographical element, relations which create a geopolitical system. [4] Critical geopolitics deconstructs classical geopolitical theories, by showing their political or ideological functions for great powers.
