The Gangetic Plains are enriched by rivers originating from the Himalayas, especially the Ganga, Indus and Brahmaputra. As these rivers flow from the mountains, they carry alluvial soil, silt and nutrients which get deposited in the plains, making the land extremely fertile. This supports abundant agriculture and allows dense human settlement. The rivers also provide water for irrigation, drinking and industry. Their consistent flow throughout the year, due to glacier melt, is vital for farming and food security.
