Is the India ocean getting bigger or smaller?

The Indian ocean is generally getting bigger due to the tectonic activity associated with the mid-ocean ridges, where new oceanic crust is formed as tectonic plates diverge. Specifically, the Indian Ocean is expanding as the African and Indian Plates move apart. However, local factors such as sedimentation and sea level changes can influence its size on a smaller scale. Overall, the long-term trend indicates a gradual increase in size.
