The Indo-Gangetic-Brahmaputra plains are the geographical area in India with the most alluvial soil deposits. This makes it ideal for farming since not only is the soil fertile, but the rivers that run across the plains provide an abundant source of irrigation. River plains are the best places for humans to live. They are densely inhabited because there is more flatland accessible for housing development and crop production. In river plains, it is also simple to build a transportation network. River plains are extensively inhabited due to the plains' fertility. As a result, creating a transportation network is much easier. Plains have a lot of flat land accessible. Furthermore, the accessible land is often fertile. As a result, plains are the most useful locations for human living and farming. Greater settlements provide cities and towns with work possibilities and a source of income, attracting people to the plains. Because the plains are located at a low elevation, the climate is often pleasant.
