The Amazon River stretches 3,980 miles across South America. Although the River Nile in Africa is the longest river, the Amazon is the largest river by discharge volume of water in the world.

There is no exact explanation of B______________. Nevertheless, most scientists agree that it was formed about 11 million years ago, C______________. One theory is that when the Andes mountain range was created 15 million years ago, the previously existing west-flowing river's route was blocked, D______________. As this lake grew in size, the marine species that could no longer reach the sea evolved into freshwater creatures. This would explain the diverse species found in the river today, E______________.
