Mantle convection and plate tectonics are well-established drivers of the supercontinent cycle, dictating the periodic assembly, breakup, and deformation of continental landmasses over hundreds of millions of years.

The analysis

The retrieved papers provide robust support for the claim that mantle convection and plate tectonics cause or govern the supercontinent cycle. Studies such as paper [2], [4], [8], and [10] explicitly link mantle dynamics, subduction processes, and tectonic regimes to the periodic assembly and breakup of supercontinents.
