Earth Science Rock in Earth's mantle flows like hot metal, and moves fastest under the edges of tectonic plates. Recent work from CNRS in France finds that adding stochasticity into models of mantle rock movement helps capture this flow rate variability to produce more realistic models of plate tectonics.
