Final answer:
The Andes mountain range is found south of the Tropic of Capricorn along the western coast of South America. The Southern Alps in New Zealand also lie south of the Tropic, while in Africa, only individual mountains and smaller ranges like the Cape Ranges are present.
Step-by-step explanation:
The mountain range located south of the Tropic of Capricorn is the Andes mountain range. Situated along the west coast of South America, the Andes extend from the northern part of the continent, through the tropical areas, and down to the southern cone, which includes parts of Argentina and Chile that are south of the Tropic of Capricorn. This region enjoys various climate zones and, despite its proximity to the equator, the Andes mountains are home to permanent glaciers.
The Southern Alps are also found south of the Tropic of Capricorn, extending along much of New Zealand's South Island. When considering Africa, however, individual mountains like Mount Cameroon or the low-lying Cape Ranges are present, but there are no extensive mountain chains in its southern regions that compare to the magnitude of the Andes.
