The Himalayas are a vast mountain range in Asia, stretching across five countries: India, Nepal, Bhutan, China, and Pakistan. They are home to some of the world's highest peaks, including Mount Everest, which is the tallest mountain on Earth. The range spans approximately 1,500 miles and features diverse landscapes, from lush valleys to rugged cliffs. The geography of the Himalayas includes various ecosystems, such as alpine meadows and dense forests. The region is also known for its significant rivers, including the Ganges, Indus, and Brahmaputra, which originate in the mountains and support millions of people downstream. The unique geography influences climate patterns and biodiversity in the area.
