The River Amazon in South America is the largest river by discharge of water in the world, and the second in length.
When rainy season arrives in South America the width of the Amazon River can reach 120 miles in width.
The river originates from the Andes mountains in the Peru.
It runs through Ecuador, Venezuela, Bolivia, Brazil, Colombia and Peru.
The length of the Amazon River is approximately 6400 kilometers (4000 miles).
The Amazon is the widest river of the world. The width of the Amazon is between 1.6 and 10 kilometers (1.0 and 6.2 miles) at low stage, but expands during the wet season to 48 kilometers (30 miles) or more.
The Amazon River serves as the main transportation route for produce and people in the regions it flows through.
The mouth of the Amazon is over 320 kilometers (200 miles) wide.
The Amazon River is second in length to the Nile River in Africa. The Nile is the longest river in the world.
The Amazon discharges 209,000 cubic meters (7,831,000 cubic feet ) every second.
The total discharge by Amazon River alone is greater than the total discharge of 7 next largest rivers of world taken together!
The Amazon basin is the largest drainage basin in the world, with an area of approximately 7,050,000 square kilometers (2,720,000 square miles), and accounts for roughly one-fifth of the world’s total river flow.
The source of the Amazon River is believed to be Lago Villafro in Peru's Andes Mountains.

The Amazon River is credited with flowing 20% of the Earth’s fresh water into the Atlantic Ocean.
This fresh water brought by Amazon River dilutes the salinity and changes the color of the ocean’s surface over an area of 2,600,000 square kilometers (1,003,865 square miles).
The Amazon River is responsible for one quarter of the fresh water that flows into the oceans worldwide. The amount of fresh water that flows into the Atlantic Ocean from the Amazon changes the water's color and salt content for approximately 320 km from the river's delta.
Amazon dumps directly into the turbulent Atlantic. Because of the high tidal energy and the strong waves, sediments from Amazon flow out into the open ocean and thus, Amazon never really forms a true delta.
There are more than 1,100 known tributaries flowing into the Amazon River. Tributaries are sources of water such as a small river, stream or other water flow that reaches the river.
Because of its vast dimensions, it is sometimes called “The River Sea“.
At least 17 tributaries flowing into the Amazon River are 1500 km in length.
