How far does Mount Everest go into the ground?

Mount Everest, the highest peak on Earth, rises about 8,848.86 meters (29,031.7 feet) above sea level. However, the mountain's base extends much deeper into the ground, as it is part of the Himalayan mountain range formed by tectonic plate collisions. The exact depth below the surface isn't well-defined, but estimates suggest that the mountain could extend several kilometers into the Earth's crust, possibly around 5 to 10 kilometers (3 to 6 miles) or more, depending on geological factors.
