One additional way that continents could have changed position over Earth's history is through the process of subduction and collision at convergent plate boundaries.
Convergent plate boundaries occur when two tectonic plates are moving towards each other. In this case, if one plate consists of oceanic crust and the other plate consists of continental crust, the denser oceanic crust will subduct (sink) beneath the continental crust. This process is known as subduction.
As the oceanic crust sinks into the mantle, it generates intense heat and pressure. This can cause the overlying continental crust to melt and generate magma. Eventually, this magma will rise to the surface, forming volcanic eruptions and igneous activity.
Over time, these volcanic eruptions can create new volcanic arcs, which are chains of volcanic islands or mountain ranges. The subducting oceanic plate continues to sink deeper into the mantle, and as the magma is erupted, new crust is added to the edge of the overriding continental plate.
This subduction and collision process can result in the amalgamation of different continental fragments, eventually forming larger landmasses. For example, the collision between the Indian Plate and the Eurasian Plate led to the formation of the Himalayan mountain range and the uplifting of the Tibetan Plateau.
Through these subduction and collision processes, continents can change their positions on Earth's surface. They can either merge together to form supercontinents, such as Pangaea, or rift apart to form separate landmasses, as with the breakup of Pangaea into the current continents.

Sure! Here's a paragraph that summarizes the concept:
Continents can also change their positions over time through the process of subduction and collision at convergent plate boundaries. When oceanic crust subducts beneath continental crust, it generates intense heat and pressure that leads to the melting of the continental crust and the formation of magma. This magma eventually rises to the surface, creating volcanic eruptions and igneous activity. As the subducting oceanic plate continues to sink, new crust is added to the edge of the continental plate, resulting in the amalgamation of different continental fragments. This subduction and collision process can lead to the formation of larger landmasses and the creation of mountain ranges like the Himalayas. Through these geological processes, continents have shifted positions, either coming together to form supercontinents or breaking apart to form separate landmasses.
