What caused the formation of Pangea?

The formation of Pangea, a supercontinent that existed around 335 million years ago, was primarily caused by the movement of tectonic plates driven by geological processes such as mantle convection. As these plates shifted and collided, they gradually merged landmasses together. This process was influenced by the Earth's internal heat, which causes the mantle to flow and create forces that pull and push the plates in different directions. Over millions of years, these movements resulted in the consolidation of continents into the single landmass we now know as Pangea.
