In the global contest of crustal thickness, the Tibetan Plateau is the undisputed heavyweight champion. The crust in its core region reaches a staggering 70-80 kilometers, compared to the mere 5-7 kilometers typically found in oceanic crust. To put this into perspective, the depth beneath your feet on the plateau is equivalent to stacking ten Mariana Trenches vertically. This extreme thickness is the "geological medal" earned from the ongoing collision between the Indian and Eurasian plates; it not only created the "Roof of the World" but also serves as the solid foundation that drives Asian climate systems and influences global atmospheric circulation.
