Continental drift is driven by mantle convection, tectonic plates, and internal Earth forces, not by water pressure at the coast.
The claim is a specific, empirical geological assertion about the primary cause of continental drift. The retrieved papers on tectonic configuration (such as Paper [1] and [6]) demonstrate that continental drift and margin deformation are caused by internal tectonic forces, mantle dynamics, and plate tectonics, entirely contradicting the notion that coastal water pressure is the primary driver. None of the provided papers support the claim.
