Geodynamics is a subfield of geophysics dealing with dynamics of the Earth. Experts in geodynamics commonly use data from geodetic GPS, InSAR, and seismology, along with numerical models, to study the evolution of the Earth's lithosphere, mantle and core.
Work performed by geodynamicists may include:
- Modeling brittle and ductile deformation of geologic materials
- Predicting patterns of continental accretion and breakup of continents and supercontinents
- Observing surface deformation and relaxation due to ice sheets and post-glacial rebound, and making related conjectures about the viscosity of the mantle
- Finding and understanding the driving mechanisms behind plate tectonics
