The Himalayan mountain range is a vast mountain system in Asia, stretching across five countries: India, Nepal, Bhutan, China, and Pakistan. It is home to some of the world's highest peaks, including Mount Everest, which is the tallest mountain on Earth, standing at 8,848 meters (29,029 feet) above sea level. The range was formed by the collision of the Indian and Eurasian tectonic plates millions of years ago. The Himalayas play a crucial role in the climate and ecology of the region. They act as a barrier to cold winds from the north, creating a warmer climate in the southern regions. Additionally, the mountains are the source of major rivers, such as the Ganges, Indus, and Brahmaputra, which are vital for the livelihoods of millions of people living in the surrounding areas.
