How Tall Can Mountains Get?

Mount Everest, at 8,848 meters, is the tallest peak on Earth, but its height is limited by tectonic forces and gravity. Mountains form through crustal movements, leading to uplift, but their growth is eventually halted by their own weight. Glacial erosion further limits mountain height, a concept known as the glacial buzzsaw. Volcanic mountains like Mauna Kea grow differently, not relying on tectonic uplift. On Mars, Olympus Mons reaches 25,000 meters due to less gravity and a stable crust, a feat not possible on Earth.
