WebJun 1, 2012 · The existence of the Earth's inner core was inferred by Lehmann (1936) from the observation of P-waves in the core shadow zone, which she interpreted as being due to the reflection of P-waves at a deep seismological discontinuity, … Geodynamics is a subfield of geophysics dealing with dynamics of the Earth. It applies physics, chemistry and mathematics to the understanding of how mantle convection leads to plate tectonics and geologic phenomena such as seafloor spreading, mountain building, volcanoes, earthquakes, faulting. It … See more Geodynamics is generally concerned with processes that move materials throughout the Earth. In the Earth's interior, movement happens when rocks melt or deform and flow in response to a stress field. This deformation may be See more The main motive force behind stress in the Earth is provided by thermal energy from radioisotope decay, friction, and residual heat.
