* Located primarily in Argentina and is bounded by Andes in west and Atlantic Ocean to its east.

Central Lowlands:




* Lie between Andes Eastern Highlands and covers more than half of continents area.
* Mostly Sparsely populated because of leached soils. But Pampas in Argentina are very fertiles.


Lowlands consists of 3 River Basins

* Llsnos Basin - created by Orinoco River and it's tributaries 
* Selvas Basin- fromed by Amazon and it's tributaries 
* Amazon - world's largest River by volume. This Basin is covered with Equatorial Rain forest ( Lungs of the world)

DIFFERENCE BETWEEN The CARABBIAN AND WEST INDIES 



The Carabian

* Caribbean Sea , it's surrounding coasts
* It's Islands ( within caribbean Sea or on the edge)
* It related to North America 
* Situated largely on the caribbean plate
* The Bahamas - sometimes considered a part of caribbean full member State of the Caribbean community 
* Mainland countries Brazil, Guyana, and Suriname considered part of caribbean - full member states of caribbean community and the Association of caribbean states

* Sorted into 3 main island groups - Lucayan Archipelagos( Bahamas) Greater Antilles and Lesser Antilles 
* West Indies was coined by Columbus when he mistakenly called aboriginal people of America ' Indians' Columbus thought he had reached Asia ( and the east Indies) . Back in Spain when his mistake was exposed, he renamed them west Indies 


Anglo American and Latin American

* Anglo - U S and Canada
