Geodynamics

Geodynamics is a branch of geophysics that studies the forces and motions inside the Earth and their effects on the surface. Geodynamics uses physics, chemistry and mathematics to understand how mantle convection leads to plate tectonics and geologic phenomena such as seafloor spreading, mountain building, volcanoes, earthquakes, and faulting. Geodynamics also explores the internal structure and dynamics of other planets. Geodynamicists use data from GPS, InSAR, seismology, and numerical models to investigate the evolution and current state of the Earth’s lithosphere, mantle and core.
