Geodynamics

Geodynamics is a subfield of geophysics dealing with dynamics of the Earth masses. Geophysics, a major discipline of Earth sciences, is the study of the Earth by quantitative physical methods especially by seismic, electromagnetic In physics the term dynamics customarily refers to the time evolution of physical processes Experts in geodynamics commonly use techniques such as geodetic GPS, InSAR, and seismology, to study the evolution of the Earth's Lithosphere, Mantle and Core. Geodesy (dʒiːˈɒdɪsi also called geodetics, a branch of Earth sciences, is the scientific discipline that deals Basic concept of GPS operation A GPS receiver calculates its position by carefully timing the signals sent by the constellation of GPS Satellites high above the Earth Interferometric synthetic aperture radar, also abbreviated InSAR or IfSAR, is a Radar technique used in Geodesy and Remote sensing Seismology (from Greek grc σεισμός seismos, "earthquake" and grc -λογία -logia) is the scientific study of Earthquakes The lithosphere (IPA, from the Greek λίθος for "rocky" + σφαίρα for "sphere" is the solid outermost shell of a rocky Planet. Convection in the most general terms refers to the movement of molecules within Fluids (i The inner core of the Earth, its innermost layer as detected by seismological studies, is a primarily solid Sphere about in radius only about 70%
