What is the difference between earths highest mountain and its deepest ocean canyon?

Earth's highest mountain, Mount Everest, reaches an elevation of about 8,848 meters (29,029 feet) above sea level. In contrast, the Mariana Trench, the deepest oceanic trench, plunges approximately 11,034 meters (36,201 feet) below sea level. This means that the Mariana Trench is over 19,000 meters (over 62,000 feet) deeper than Mount Everest is tall, highlighting the extreme variations in Earth's topography.
