Explanation
Glaciers form in cold regions where snow accumulates faster than it melts. Glaciers move slowly downhill, carving valleys and shaping landscapes. Glaciers store about 69 percent of Earth's fresh water. Many major rivers originate from glaciers. The Himalayas contain major glaciers that feed rivers like the Ganges, Brahmaputra, and Indus. Glaciers are retreating due to global warming, affecting water supply downstream.
Example
The Siachen Glacier in the Karakoram Range is one of the world's largest glaciers and is the source of many streams.
