How is sunderban delta formed?

The Sundarbans Delta is formed by the deposition of sediment carried by the Ganges, Brahmaputra, and Meghna rivers as they converge and flow into the Bay of Bengal. This process is influenced by tidal actions, riverine siltation, and coastal erosion. Over time, these sediments accumulate, creating a complex network of islands, mangroves, and estuaries. The unique ecosystem that arises supports diverse wildlife, including the famous Bengal tiger.
