The movement, formation, or re-formation of continents explained because of the theory of dish tectonics.
The slow activity of continents explained by dish tectonics.
the slow (ca. 1-5 cm per year) movement of the continents and parts of continents relative to one another and also to the points of upwelling of magma in the viscous layers underneath the continents; -- causing, for instance, the orifice of Southern Atlantic Ocean by the activity of Africa and South America far from one another. See in addition plate tectonics.
the gradual motion and development of continents (as described by plate tectonics)
