喜馬拉雅山脈是世界海拔最高的山脈,位於亞洲的中國與尼泊爾之間,分佈於青藏高原南緣,西起克什米爾的南迦-帕爾巴特峰(北緯35°14'21",東經74°35'24",海拔8125米),東至雅魯藏布江大拐彎處的南迦巴瓦峰(北緯29°37'51」,東經95°03'31」,海拔7756米),全長2400公里。主峰珠穆朗瑪(Everest)海拔高度8844.43米。 根據板塊構造學,喜馬拉雅山脈是由印度板塊與歐亞大陸板塊碰撞形成的。 所以現在喜馬拉雅山仍然在緩慢上升中。喜馬拉雅山脈約有70多個山峰。

山區冰河
全球有七成的淡水是凍結於冰河中,而喜馬拉雅山區的淡水集中量,是南北極以外最多的地區。喜馬拉雅山區冰河供應諸多亞洲河流所需的淡水,包括黃河、長江、恆河、印度河、湄公河等等。
在聖母峰附近曾經測得的最低溫為零下60℃,但是自1970年代以來,由於山區的平均氣溫上升了1℃,使得山區冰河正大量縮減消融,冰河的迅速消退不但會先使河流的水位暴增,造成洪澇;幾年之後河水水位將會下降而形成乾旱或是更嚴重的生態問題。許多學者已經向聯合國提議將聖母峰及其周圍地區列為「全球受氣候變化衝擊的危險地區」。
The Himalayas (also Himalaya, Sanskrit: हिमालय, IPA pronunciation: [hɪ'mɑlijə], [ˌhɪmə'leɪjə]) are a mountain range in Asia, separating the Indian subcontinent from the Tibetan Plateau. By extension, it is also the name of the massive mountain system which includes the Himalaya proper, the Karakoram, the Hindu Kush, and a host of minor ranges extending from the Pamir Knot. The name is from Sanskrit himālaya, a tatpurusa compound meaning "the abode of snow" (from hima "snow", and ālaya "abode"; see also Himavat).[1]
Together, the Himalaya mountain system is the planet's highest and home to the world's highest peaks: the Eight-thousanders, including Mount Everest. To comprehend the enormous scale of Himalayan peaks, consider that Aconcagua, in the Andes, at 6,962 m, is the highest peak outside the Himalaya, while the Himalayan system has over 100 separate mountains exceeding 7,200 meters.
The Himalayas stretch across six nations: Bhutan, China, India, Nepal, Pakistan and Afghanistan. It is the source of three of the world's major river systems, the Indus Basin, the Ganga-Brahmaputra Basin and the Yangtze Basin. An estimated 750 million people live in the watershed area of the Himalayan rivers, which also includes Bangladesh.

Satellite photographs (from Terra-MODIS) and computer-generated models help visualize Bangladesh's place in the world. Located in South Asia, it is virtually surrounded by India and the Bay of Bengal to the south. But in many ways, the country's fate is dominated by the world's highest mountain range looming to the north-the Himalayas.

The himalayas, geologically young and structurally fold mountains stretch over the northern borders of India.These mountain ranges run in a west-east direction from the Indus to the Brahmaputra.The Himalayas represent the loftiest and one of the most rugged mountain barriers in the world. They form an arc, which covers a distance of about 2,400 Km.Their width varies from 400Km in Kashmir to 150Km in Arunachal Pradesh.The altitudinal variations are greater in the eastern half than those in the western half.The himalayas consists of three parallel ranges in its longitudinal extent.A number of valleys lie between these ranges.The northern-most range is known as the Great or Inner Himalayas or the 'Himadri'.
