Final answer:
The Andes Mountains, Amazon Rainforest, and Patagonia desert are significant physical barriers to Latin America's development, affecting transportation, agriculture, and population distribution.
Step-by-step explanation:
Physical barriers to development in Latin America include the Andes Mountains, the Amazon Rainforest, and the vastness of the Patagonia desert. The towering Andes present challenges to transportation and communication, hindering access to resources and isolating communities.
The dense, biodiverse Amazon Rainforest, while a treasure trove of natural resources, complicates agricultural expansion, infrastructure development, and poses health challenges due to its vast, remote areas. Finally, the arid Patagonia region is sparsely populated due to its harsh climate and limited water sources, making economic development difficult.
