Mount Everest Summit

The highest point on Earth is the size of a dining table/Mountains

The summit of Mount Everest is a snow-covered area roughly the size of two ping pong tables, about 5 square meters, at an elevation of 8,849 meters. Air pressure at the summit is about one-third of sea-level pressure, providing only a third of the normal oxygen. The summit rock is marine limestone, meaning the top of Earth's tallest mountain was once at the bottom of an ancient sea.
