What is the highest mountain in the world?
The highest mountain on Earth is Mount Everest, located in Nepal. It stands at an altitude of 8,867 meters (29,966 feet) and was first climbed by Sir Edmund Hillary and Tenzing Norgay in 1953.

There are several other mountains that are higher than Everest, including K2, which sits near its border with Pakistan and has an altitude of 26,222 meters (85,366 feet). However, these peaks are not technically considered to be true mountains because they do not have permanent snow or ice cover.

In terms of sheer height, it's worth noting that many people consider Kilimanjaro in Tanzania to be the world's tallest mountain due to its exceptional visibility and accessibility. But like Everest, Kilimanjaro is a peak that is primarily composed of rock rather than ice or snow. So while it may stand high in the rankings, it doesn't quite reach the same level of awe-inspiring majesty as some of the more famous Himalayan ranges.
