What is the tallest mountain in the world?

Mount Everest holds the title of the tallest mountain in the world, reaching an impressive height of 8,848.86 meters (29,031.7 feet) above sea level. This height was officially recognized following a survey by Nepal and China in 2020, which confirmed its elevation. Mount Everest is part of the Himalayas, located on the border between Nepal and the Tibet Autonomous Region of China. Its majestic height makes it a significant landmark and an iconic destination for climbers and adventurers from around the globe.

In contrast, K2, Mount Kilimanjaro, and Mount McKinley (now known as Denali) are all notable peaks, but they do not surpass the height of Mount Everest. K2 is the second-highest mountain at 8,611 meters, while Mount Kilimanjaro stands at approximately 5,895 meters. Denali, the highest peak in North America, reaches 6,190 meters. Each of these mountains is remarkable in its own right, but when discussing the tallest mountain in the world, Mount Everest is unequivocally the correct answer.
