The Indian ocean formed as a result of the breakup of the supercontinent Gondwana, which began around 180 million years ago during the Mesozoic era. Tectonic plate movements caused the landmasses to drift apart, leading to the development of oceanic crust and the widening of the ocean basin. This process involved seafloor spreading at mid-ocean ridges and the subduction of oceanic plates, shaping the ocean's current boundaries and geological features. The Indian Ocean continues to evolve due to ongoing tectonic activity.
