Dynamics in the rocky mantle of Mars
Dynamics in the rocky mantle of Mars
This thermal evolution model illustrates the dynamics of Mars’s rocky mantle. Warm colours represent hot thermal anomalies, known as mantle upwellings or mantle plumes, which transport heat from the planet’s deep interior towards the surface. Cool colours represent cold material sinking and cooling the interior of the planet. New scientific findings show that Mars’s mantle is highly viscous. The surface map is based on the US Geological Survey’s Viking Global Colour Mosaic.
