Plate tectonics
= Plate tectonics
{wiki}
A mobile-lid mode of planetary evolution in which coherent pieces of the <lithosphere> move, form at spreading regions and can recycle through <subduction>. <Slab pull>, <ridge push> and mantle flow compete with deformation resistance. It affects heat transport, <volcanism>, <earthquakes> and the <carbonate-silicate cycle>. It is not guaranteed solely by an <exoplanet>'s mass.
