What set apar pangaea?

Pangaea began to break apart during the Mesozoic Era, around 175 million years ago, due to the movement of tectonic plates driven by mantle convection. This process caused rifting and the formation of new ocean basins, leading to the gradual separation of continents. The fragmentation was influenced by geological forces, including volcanic activity and earthquakes, which reshaped the Earth's surface and facilitated the drift of landmasses to their current positions.
