Answer:
the Andes
Step-by-step explanation:
The world's longest above-water mountain range is the Andes, about 7,000 km (4,300 mi) long. The range stretches from north to south through seven countries in South America, along the west coast of the continent: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The only mountains that are taller than the Andes are the Himalaya Mountains and their adjacent ranges, including the Hindu Kush. The average elevation in the Andes is about 13,000 feet (3,962 meters). The highest elevation in the Andes is Mount Aconcagua in Argentina, which is 22,841 feet (6,962 m) above sea level.
