I suspect the earth has a more dynamic composition than does Venus because of the widely held idea that a large body crashed into the early earth and that kinetic energy threw off enough material to coalesce into our moon. The combination of heat from the impact and the gravity of the moon pulling on the crust give our world the moving crustal plates.
