The Himalayas is a mountain range in the middle of Asia. They form the separation between the plateaus of the Tibetan Plateau in the north and the river plains of the Indian Subcontinent in the south. In the broad sense, adjacent mountains such as the Karakoram, Hindukush, Pamir and Kunlun are counted among the “Greater Himalayas”. All these mountains belong geologically to the same system. If only the actual Himalaya is considered, the total length is around 2500 km. The width varies between 200 and 400 km. The mountain range contains more than 40 peaks above 7000 meters and 9 peaks above 8000 meters. Below it is the highest mountain in the world, the Mount Everest (8850 m  high). The Himalayas are governed by the great powers of India and China (Tibet) and the smaller mountain countries of Nepal and Bhutan. The extreme west of the mountain finally falls under Pakistan. The Himalayas is the source of some of the largest rivers in Asia, providing hundreds of millions of people with drinking water.
