What caused the Andes range in South America?
The Andes are the result of tectonic plate processes, caused by the subduction of oceanic crust beneath the South American Plate. It is the result of a convergent plate boundary between the Nazca Plate and the South American Plate.
What is the most likely cause of the formation of the Andes mountains in South America quizlet?
the Andes were formed from a plate that is subducting at a steep angle compared to the subduction zone that formed the Rocky Mountains.
How are the landforms of the region both an advantage and disadvantage?
How are the landforms of the region both and advantage and disadvantage? the mountains provide protection for settlements but made it hard to cross the continents; the rivers also made traveling difficult. The landforms also resulted in rich soil that is good for planting and grazing and lots of natural resources.
What are the Andes used for?
The Andes help feed the world Potatoes and tomatoes, two of the most widespread crops on our planet, originated from the Andes. Over 3,800 different types of potatoes are grown in Peru alone. Coca leaves also famously originate from the western slopes of the Andean mountains.
How do the Andes affect the climate of South America?
The Andes have a direct mechanical influence on the climatology of South America by forcing orographic precipitation along the eastern flanks of the Andes, and blocking westerly flow from the Pacific.
What effects does altitude have on the climate of the Andean countries of South America?
The higher the altitude the cooler the temperature. Also the oxygen is thin. What is the relationship between altitude and climate in the Andes? How are the climates in the mid-latitude countries of South America different from those in the Andean region?
Which of the following best explains the area of the Andes mountains that would have the greatest number of rivers?
Based on the map, which of the following best explains the area of the Andes Mountains that would have the greatest number of rivers? More rivers would be located on the east side of the Andes Mountains because the trade winds are coming from the east.
What plate movement caused the Andes mountains?
The mountains have been formed as a result of the convergence of the Nazca plate and the South American plate. The heavier oceanic crust of the Nazca plate is pushed towards the South American plate, and because it is denser is subducted underneath.
How did the Andes mountains affect the western coast of South America?
The Andes Mountains were an obstacle to moving inland along the west and south coasts of South America. This is the reason why people settled more on the north and east coasts of South America.
What are the advantages of mountains?
They help us by improving air and water quality they are a refuge for biodiversity they help reduce erosion in areas of steep terrain and they are obvious physical barriers protecting us from natural disasters such as landslides mudflows or rockslides.
How do the Andes mountains affect the climate of South America?
The Andes have a direct mechanical influence on the climatology of South America by forcing orographic precipitation along the eastern flanks of the Andes, and blocking westerly flow from the Pacific.
What effect does altitude have on the climates of the Andean countries of South America?
The ranging mountains, plains, and other landforms in the Andean region and Midlatitude countries of South America mean that the regions climate is extremely diverse. What is the relationship between altitude and climate in the Andes? The higher the altitude the cooler the temperature. Also, the oxygen is thin.
How does the Andes mountains affect climate?
Because the Andes act as a large wall between the Pacific Ocean and the continent, they have a tremendous impact on climate in the region. The northern part of the Andes is typically rainy and warm, and the weather is also wet in the eastern part of central Andes, and the area to the southwest.
How does the Andes mountains impact humans?
The Andes always have been a formidable barrier for communication, with great effect on the economic and cultural development of the region. Production centres generally are far from seaports, and the mountainous character of the land makes the construction and maintenance of railways and roads difficult and expensive.
Why is the Andes mountain range important?
The Andes play a vital part in national economies, accounting for a significant proportion of the region's GDP, providing large agricultural areas, mineral resources, and water for agriculture, hydroelectricity (Figure 1), domestic use, and some of the largest business centres in South America.
What are the factors affecting the climate of South America?
Latitudinal position, presence of mountain ranges, ocean currents and its distance from the sea are the main factors which affect the climate of South America.

How do mountains affect the environment?
The mountains create a barrier to air moving eastward off the Pacific Ocean. When the moist, oceanic air encounters the mountains it begins to rise. The rising air cools as it moves up and over the mountains, and much of its moisture condenses, forming clouds and precipitation.
What is the impact of mountains?
Mountains provide for the freshwater needs of more than half of humanity, and are, in effect, the water towers of the world. The world's mountains encompass some of the most spectacular landscapes, a great diversity of species and habitat types, and distinctive human communities.
Where are the Andes mountains in South America?
The mountain range spans seven countries — Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina — and can be found between 10 degrees north and 57 degrees south latitudes and 70 degrees to 80 degrees west longitude. It is up to 500 miles (804 km) wide.

How does the Andes affect the climate of South America?
The Andes have a direct mechanical influence on the climatology of South America by forcing orographic precipitation along the eastern flanks of the Andes, and blocking westerly flow from the Pacific.
What negative effects do the Andes mountains cause?
Mining. Mining for copper, gold, silver and other minerals affects large areas of the hotspot. This extractive activity occurs both legally and illegally and has a huge impact on habitat loss, degradation and contamination of soils and water courses.
How do the Andes affect climate?
Because the Andes act as a large wall between the Pacific Ocean and the continent, they have a tremendous impact on climate in the region. The northern part of the Andes is typically rainy and warm, and the weather is also wet in the eastern part of central Andes, and the area to the southwest.
How does the shape of the continent affect the climate of the southern part of South America?
Solution. Due to its tapering size or shape, the southern part of South America gets the moderating influence of the oceans and thus has mild climate.
How do mountains affect?
Mountains can affect the climate of nearby lands. In some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. Much of airborne moisture falls as rain on the windward side of mountains.
How do mountains affect the ecosystem?
Because of their height, mountains act as water towers, diverting air masses and forcing them to rise, cool and fall as rain or snow. Water flowing from mountains doesn't just provide essential drinking water; it also sustains food production for more than half of the world's population.
What is the Andes mountains in geography?
The Andes Mountains are a series of extremely high plateaus surmounted by even higher peaks that form an unbroken rampart over a distance of some 5,500 miles (8,900 kilometres)—from the southern tip of South America to the continent's northernmost coast on the Caribbean.
What problems do mountains cause?
A new U.N. report finds that mountains and the societies that call them home face their own suite of climate challenges. They include temperature and precipitation extremes, which in turn can trigger avalanches, flooding, drought and wildfire.
How do people impact the Andes mountains?
Population pressure and migration are deforestation drivers caused by the increasing need for new and greater areas for agricultural production and an increasing demand for food, water and energy by large populations in distant urban centers as well as in Amazonian communities.
