Mount Everest sits on the crest of the Himalayas, exactly on the international border between Nepal and the Tibet Autonomous Region of China. Geographically, it is the highest point in the world above sea level. It is a fold mountain composed largely of marine sedimentary rocks (like limestone) that were originally at the bottom of the Tethys Sea. The extreme altitude creates a “Death Zone” above 8,000 meters where oxygen is insufficient for human life. Its location makes it a focal point for global geography, serving as the ultimate symbol of the power of tectonic plate movements.
