FAQs about South America's Physical Geography

Physical features of South America include high mountain ranges, huge areas of tropical rainforest, long river systems, vast plateaus, large plains, arid deserts, large areas of fresh water including wetlands, and coastlines. The Andes mountain range, the world’s longest, is found along the western edge of South America stretching over 7,000km through seven countries in the region. The Andes have some of the highest peaks in the world and are home to over 40 active volcanoes, numerous glaciers, and many unique ecosystems. The great river systems of the continent include the Amazon, the Paraná, the Orinoco, the São Francisco, the Paraguay and the Uruguay rivers. The Amazon River is the world’s largest river in terms of discharge of water and flows through the world’s greatest tropical rainforest, the Amazon.
The Andes is the longest continental mountain range in the world. It measures over 7,000 km and extends through 7 countries in South America – all of them are on the western side of the continent. This mountain range is home to some of the highest peaks and active volcanoes in the world. The highest peak outside of Asia is Aconcagua (6,962 m) and it is located in the Andes as well. In addition to the Peaks and Volcanoes, the Andes are home to large glacier fields, cloud forests, high-altitude wetlands, tropical valleys and scrublands. The Andes have a huge geophysical and ecological influence on South America. For example, it affects the climate, it provides water for consumption and for irrigation, it is the base for agriculture and for the mining industry.
A geographical survey of South America, in terms of natural resources and physical features, must highlight the enormous presence of rivers. In fact, there are some of the greatest in the world: the Amazon River, the largest single river in the world in terms of the volume of water it annually conveys, is located at the heart of the world’s greatest tropical rainforest; the Paraná River, the Orinoco, the São Francisco, the Paraguay and the Uruguay rivers are but a few examples of a whole series of rivers, which not only provide an enormous amount of fresh water but also fish, land to be cultivated, electricity from hydroelectric power plants, means of transport and so on.
The large plains, high plateaus and arid deserts of South America include the Brazilian Highlands and the Guiana Highlands as well as the Altiplano Plateau, the Pampas, the Llanos and Patagonia. The arid Atacama Desert in northern Chile is also located on the continent. These large areas of land are used for agriculture, provide a base for large amounts of livestock and have extensive mineral resources. Every region of South America has a distinct culture and a unique environment.
The Amazon Rainforest is the world’s largest tropical rainforest and is found in the northern part of South America. The Amazon Rainforest is mostly in Brazil but extends into other countries of South America as well. The Amazon Rainforest is made up of millions of different plants and animals and the trees contain a huge amount of carbon. The Amazon Rainforest also affects the weather in the area where it is found as well as around the world. The Amazon Rainforest is also responsible for creating a large portion of the world’s oxygen and is home to many different indigenous communities and animals.
Major mountain ranges, plateaus, plains, valleys and river systems such as those of South America were formed through physical processes including tectonic movement, volcanic activity, weathering and erosion, glaciation and the transport and deposition of sediments. The Andes continue to rise as the result of the ongoing process of plate collision between the Nazca and South American plates and the South American continent is currently undergoing very significant change as the result of ongoing processes of river erosion etc.
