Plate tectonics.
The continents joined into the supercontinent Pangaea because of long-term motion of Earth's lithospheric plates (continental drift, collisions and suturing). Pangaea later broke apart when those same plate motions caused rifting, seafloor spreading and new plate boundaries to form. Glaciers and greenhouse gases are climate factors, and earthquakes are effects of plate motions, not the primary cause of forming or splitting a supercontinent.
