Amazon :: science

AmazonThe Amazon River is the second longest river in world. The headwaters begin high in the soaring Andes Mountains and stretches 6,400 km across the South American continent to the Atlantic Ocean. It discharges between 34 to 121 million liters of water per second, and depositing an average of 3 million tons of sediments near its mouth. The outpouring of water and residue is so immense that the salt content and the color of the Atlantic Ocean are altered for a distance of about 320km from the mouth of the river. Also, unlike m some(prenominal) otherwise rivers its wide and straight from the headwaters to the mouth. During a new or full moon, a wave front from the ocean sweeps 650km upstream at speeds of 65km/h and this causes waves as high as 5m. Because of its vastness, annual floods, and navigability, the Amazon River is often c solelyed the Ocean River. The Amazon River is the largest and wettest tropical plain on Earth with heavy rains. Europeans were not the original keepers of this vast rainforest. The Amazonians are trapped between the old and new customs, and since they have traditions, their technology isnt as modern as the rest of the worlds. They live on the risqueest institute with a wide variety of flora and fauna. With such great resources, including the river as transportation, almost anybody would want to seize the land and gain profits easily. The Amazonians have lesser power to defend themselves with spears against their guns. Unfortunately, the outside world has brought them diseases that are incurable with their own medicine. They cannot exist in the way they were before, but they know the Amazon better than any of us. If the rich businessmen listened to them instead of stealing from them, they might be able to improve the usage of the Amazon. All the tributaries merge into the Amazon River, but not all have an identical color. White-water rivers, the ice and snow from the Andes Mountains washes off soil nutrients from the rocks, allo wing the water to have a dirty yellowish color. Clear-water rivers are azure-green in color they precisely contain any sediment. These rivers arise from the highlands that are created by hard rock that doesnt easily erode. Dark black-water river of the Rio Negro washes over old rocks, which are rich in minerals. The name Amazon just isnt any old name.
