Sediments in Amazon River Mouth and Along Shore of French Guiana and Amapá, Brazil0.6N 49.8W
Dense brown sediments spill out of the mouth of the Amazon River and line the coastline of the Brazilian state of Amapá and French Guiana (upper left corner).
At 4,080 miles long, the Amazon is the second longest river in the world after the Nile. It runs from the Andes Mountains in Peru through Brazil to the Atlantic Ocean. It contains more water than any other river in the world- more than the Mississippi, the Nile and the Yangtze combined. In one second the Amazon pours more than 55 million gallons, or 600,000 cubic meters of water, into the Atlantic Ocean, which dilutes the ocean’s saltiness for 100 miles from shore.
