query: What is the tallest mountain in South America?
passage: Aconcagua
Aconcagua (Spanish pronunciation:[akoŋˈkaɣwa]), with a summit elevation of 6,960.8 metres (22,837ft), is the highest mountain in both the Southern and Western Hemispheres.[1] It is located in the Andes mountain range, in the Mendoza Province, Argentina, and lies 112km (70mi) northwest of its capital, the city of Mendoza, about fivekm (3.1mi) from San Juan Province and 15km (9.3mi) from the international border with Chile. The mountain itself lies entirely within Argentina, immediately east of Argentina's border with Chile.[3] Its nearest higher neighbor is Tirich Mir in the Hindu Kush, 16,520 kilometres (10,270mi) away. It is one of the Seven Summits.
passage: A Beautiful Planet
The movie demonstrates another superlative by showing a snow-capped segment of South America's Andes, "the longest [continental] mountain range in the world." Because they stretch across so much varied terrain as they wrap around the globe from Venezuela north of the Equator, through the Tropics, and down to southern Argentina, the Andean Mountains have their own superlatives: they contain "some of the most extreme climate zones on Earth, from ice fields to deserts," and they include Aconcagua, the highest peak in The Americas, as well as the highest in the Southern Hemisphere.
