Brazil's physical features
Brazil has two main physical features: Its rivers and its mountains.
There are lots of rivers in Brazil, but by far the biggest is the amazon. It is 6577km long, making it the second longest in the world, only to the nile. It has a HUGE basin of 5.8 million square km. Even though it has over 1000 tributaries, there is not one bridge over it! Other large rivers include the parana and the Sao Francisco.
Therea are only one range of mountains in Brazil: The Brazilian Highlands. They rise very sharply from the coast, forming a strip of land forming The Great Escarpment. One of the highest (and most famous) is Sugar Loaf mountain, near Rio De Janeiro.
