What is the tallest mountain in the world?
According to mountaineering organizations, the tallest mountain on Earth is Mount Everest. However, many people also consider Kilimanjaro, located in Tanzania, to be among the highest mountains in the world due to its relative accessibility and the fact that it was first climbed by George Mallory and Andrew Irvine in 1922. Additionally, some climbers argue that Cho Oyu, located in Nepal, deserves recognition as the world's third-tallest peak because of its unique shape and challenging technical climbing conditions.
