Enormous Water Amount
The Amazon is certainly not classified as an ocean, but there are big navy vessels that are able to set anchor along its shores after passing through its deeper segments. How is this possible?
Imagine the Amazon and northern South America as a cavernous dish-bowl situated at the lowest portion of the landmass. It's natural that the water will flow down into this basin, hence giving the Amazon its enormous water quantity.
How is such volume possible? Bear in mind that the Amazon River is situated near the equator, where it is has a warm and tropical climate. During the dry season, almost 42,500 square miles (110,000 km) of land are covered by water. However, come wet season, this basin will rise to triple its original number--exceeding an astounding 135,000 square kilometers!
In fact, the Amazon gathers water from 40 percent of the continent’s body of land. Together with its topography and amount of rainfall, it is the sheer territory of the river that creates this amazing natural wonder.
