The lithosphere, which comprises the Earth’s crust and the rigid upper part of the mantle, varies greatly in thickness. It is generally thinnest under oceanic ridges (around 10 km) and thickest under stable continental interiors (cratons) and mountain belts formed by continental collision, where it can exceed 150-200 km.
Continental lithosphere is generally much thicker than oceanic lithosphere. Major mountain ranges formed by collision, like the Himalayas, involve significant thickening of the crust and the underlying lithospheric mantle, leading to greater overall lithospheric depth compared to oceanic areas, plains, or deserts.
