Geology 101, by Ian Neuss
To illustrate this, put your hand (India) on a table cloth (Asia) and push it. The cloth folds about your hand. The troughs near your fingertips represent the rivers and the folds. The mountains we are now seeing are broken by faults, or sliding over each other when the stresses are too great, and causing earthquakes.
The Tibetan Plateau is a basin bounded by mountains being pushed up by India coming north. Six of the largest rivers draining the Plateau, the Indus, the Brahmaputra, the Salween, the Mekong, the Yangtze and the Yellow are the home of over half the worlds population.
