Which mountain range is the highest above sea level?

The Himalayas are the highest mountain range on Earth above sea level. They include the world’s tallest mountain, Mount Everest, which stands at 8,848.86 meters, according to the Nepal-China 2020 measurement. Fourteen peaks in the Himalaya and adjacent Karakoram range exceed 8,000 meters, making this region uniquely extreme. The range was formed by the ongoing collision of the Indian and Eurasian tectonic plates, a process that began around 50 million years ago. The Himalayas are still rising slowly today because the plates continue to converge.
