Argentinian Physical Geography

By: Zachary B, Sukanya B, Asutosh D.

Capital: Buenos Aires

Buenos Aires is the capital of Argentina as well as being the largest city in number of people living there. It is located at 34 degrees south, 58 degrees west on the GPS coordinate scale as its latitude is 34 S and its longitude is 58 W.

Relative Location

Argentina is located in South America which is below North America and the United States. It is south of Brazil and Peru, other South American countries, and is really close to Antarctica, a frozen mass of ice and snow at the south pole. It borders two oceans, mainly the Atlantic ocean but also the Pacific.
Seasons of Argentina

Cause of Seasons

The primary cause of the seasons in Argentina is that its location is far enough away from the center of the Earth or equator to experience the tilt of the Earth in its orbit. This allows the temperature to change influencing which seasons are occurring. Because Argentina is located in the southern hemisphere it experiences the opposite seasons of the United States which is in the Northern Hemisphere.

Physical Features

Calchaquí Valley

Wind slowly eroded away a series of valleys throughout the region. As the soil was mostly dust it was easy for the wind, which was strong to weather the rocks into their shapes, these two things were required. The valleys will continue to become more defined as wind weathers away the dust and stone.

Climate of Argentina

Argentina's climate is mostly humid subtropical which means there is a large portion of precipitation and a lot of plants including large trees, many types of vines, grasses, and moss. Animals also thrive in this climate type including snakes, monkeys, and some larger animals including cattle. This is in the north part of the country. There is also a portion of desert that is in the south of the country that makes up the semiarid section of little plants but a lot of heat and sand.

The Biomes of Argentina

  • tropical rain forest

    • Since Argentina is located in the subtropical high area, there is often not enough rainfall to make a rainforest.

    • The very northern tip near Uruguay and Bolivia are were very small clusters of tropical rainforest remain in Argentina

    • rainfall from 200 to 1000 cm of rain yearly

  • grasslands

    • usually very dry but has a rainy season

    • wild grasses and shrubs thrive here

    • yearly rainfall from 50 to 90 cm

    • air is usually very dry due to high air pressure, but rainfall is still not as low as in deserts

  • temperate deciduous forest

    • As most of the forests are in Chile, the Argentine forests are near the Chile-Argentina border.

    • The temperatures of these places are usually much colder in the winter and warmer in the summer causing broadleaf plants to grow here.

    • The forests are exposed to both warm and cold air masses, so the area gets all four seasons letting the plants survive the cold winters.

    • This biome is in the very west of Argentina near Chile. Like the tropical rain forest, it is not a very prominent biome in Argentina.

    • yearly rainfall from 75 to 150 cm

  • wetlands

    • caused by runoff from rivers or excessive rainfall

    • the Parana River and its tributaries go through the Ibera wetlands, which is the primary region of wetlands

    • ground becomes filled with water and overflows into the land

    • in the north eastern part of Argentina

  • desert

    • Largest biome in Argentina, takes up most of the Eastern side.

    • The high pressure in this region causes the air to be very dry

    • little to no rainfall with long periods of drought

    • hot, dry summers and cold, dry winters.

Natural Disasters in Argentina!

Argentina is a country exposed to many natural disasters such as earthquakes, severe storms, and volcanic eruptions. The three most prominent ones are the devastating floods, dangerous storms, and rattling earthquakes.


Flooding is the most common natural disaster in Argentina. A total of more than 89 floods have been recorded, causing countless people to die, and the nations economy to have a huge downfall. The main source of these floods are the Paraná, the Paraguay, and the Uruguay rivers. The wetlands are the most common place for the floods. More than 80% of Argentinas populations lives near the valleys of these rivers. The main cause of these floods is the large amount of rainfall, that is brought from the sky by the climates of Argentina.


Storms are all over the place in Argentina. They aren't the storms like we have here at home. The ones in Argentina are very dangerous and can be deadly. One storm in average pours down more than 400 millimeters of rain. That much rain usually takes over 6 months! The main cause of these storms/thunderstorms are hidden in the sky. Different forms of air converge and overturn, causing big clouds to form, and then the hail, rain and powerful rains start coming in. These storms also cause the flooding that the Argentinians face.

Earthquakes! BOOM!

We all know earthquakes are scary. Really scary. Think about it, an earthquake that randomly occurs while your in the toilet. Scary. If you live in Argentina, that might just happen. These earthquakes have destroyed the cities of Argentina completely, killing more than 10,000 people. Earthquakes cause great loss of materials, and the nation loses a lot of money when they start re-building the city. So, what causes these earthquakes? The earth has tectonic plates, which is the land you and I stand on. These plates are moving constantly, and sometimes, they bump into each other that causes these earthquakes. The tectonic plate that these earthquakes come from is called the South American Plate, that resides in the left center of South America.
