Track down the Brahmaputra river valley, animated satellite image. North is at top. At the start of the clip, the Tibetan plateau (brown, top left), meets with the Himalayas (white) below it. Small rivers carrying Himalayan meltwater flow into the valley of the large Brahmaputra river in Assam, India. The Brahmaputra crosses the Indian border into Bangladesh and joins the Ganges river (running from left to lower centre) to eventually flow into the Ganges delta (pale brown and blue, bottom).
