Without question, Brazil stands at the top of the list as the largest country in South America and the fifth largest in the world. It covers an area of approximately 8.5 million square kilometers, making it more than double the size of the next largest country on the continent. Brazil alone occupies almost half of South America’s total landmass.
Geography and Environment
Brazil’s size gives it an incredibly varied geography. The Amazon Rainforest, one of the most biodiverse regions on Earth, spreads across the north of the country. The Amazon River, which rivals the Nile in length and surpasses it in water volume, courses through this immense forest, nourishing countless species. In the central region, the Cerrado savannahs dominate, while the south features subtropical grasslands known as the Pampas. Along the Atlantic coast, sprawling beaches and major cities define the landscape.
The country is also home to the Pantanal, the world’s largest tropical wetland, famed for its wildlife including jaguars, capybaras, and caimans.
Population and Culture
Brazil’s population exceeds 200 million, making it the most populous nation in South America. Its cultural identity is a blend of indigenous, African, and European influences. Portuguese is the official language, distinguishing Brazil from its Spanish-speaking neighbors. Samba, bossa nova, and carnival are cultural expressions that have gained worldwide recognition.
Economy and Global Role
Economically, Brazil is a powerhouse, classified as one of the BRICS nations. It has a strong agricultural sector, producing coffee, soybeans, sugar, and beef at global scales. Its natural resources include iron ore, oil, and timber. Brazil is also an emerging leader in renewable energy, particularly biofuels.
2. Argentina – The Land of the Pampas
Argentina is the second-largest country in South America and the eighth largest in the world, spanning approximately 2.78 million square kilometers. Its landmass stretches from subtropical regions in the north to the windswept plains of Patagonia in the south.

Bolivia’s landscape is dominated by the Andes Mountains, which split the country into distinct regions. The western highlands feature the Altiplano, a vast plateau that sits at an average elevation of 3,600 meters above sea level. This region is home to Lake Titicaca, the highest navigable lake in the world, shared with Peru.
In contrast, the eastern lowlands form part of the Amazon basin, with tropical rainforests, savannahs, and wetlands. The Salar de Uyuni, the world’s largest salt flat, is another iconic feature of Bolivia’s geography.
