What is the tallest mountain in the world?

Mount Everest is recognized as the tallest mountain in the world, with its peak reaching an elevation of 8,848.86 meters (29,031.7 feet) above sea level. This measurement has been confirmed by various geological surveys and is widely accepted in the scientific community. Mount Everest, part of the Himalayas, is located on the border between Nepal and the Tibet Autonomous Region of China.

The distinction of being the highest point on Earth is determined by its elevation relative to sea level, which is why Mount Everest holds this title. Other mountains, such as Mount Kilimanjaro and K2, while significant in stature and famous for their unique challenges, do not exceed the height of Everest. Mount McKinley, also known as Denali, is the tallest mountain in North America but is considerably lower than Everest. Thus, Mount Everest's height and geological significance firmly establish it as the tallest mountain in the world.
