A river is a natural stream of water that flows continuously. It is difficult to know precisely the length of a river, since for this it is necessary to determine exactly where it is born and where it flows.
Amur (4,410 km): It flows through northeastern Asia along more than 4,410 km from the mountains of northwestern China to the Sea of Okhotsk (near Nikolayevsk-na-Amure), in Russia. It is very abundant and crosses different climates (desert, steppe, tundra, and taiga). Strictly speaking, the Amur measures 2,874 km after the union of two other rivers: Shilka and Argun.
Yellow River or Huang He
Yellow River or Huang He (5,464 km): It is the second longest river in China, only surpassed by the Yangtze River (Blue). The river is born on the high plateau of Tibet and Qinghai, in the Kunlu Mountains, at an altitude of 4,500 m. From there it crosses the Chinese provinces of Qinghai and Gansu, moving north to the Ordos desert in the Inner Mongolia Autonomous Region. It flows from a fran delta into the Gulf of Bohai (Yellow Sea), on the east coast of China.
Lena (4,260 km): From the 1,640 m altitude of its origin in the Baikal Mountains, south of the Central Siberian Plateau, 20 km west of Lake Baikal, the Lena flows to the northwest, and the Kirenga and the Vitim. The southwest of the New Siberian Islands flows into a delta of 10,800 m2, crossed by seven main branches, the most important being the Bylov, the most eastern.
Congo (4,380 km): It is the largest river in central Africa. It has a length of 4,380 km, which makes it the second longest in Africa (after the Nile). The Congo basin covers an area of 3,700,000 km². The river and its tributaries cross the second largest jungle in the world, after the Amazon. The Congo is also the second largest river in the world after the Amazon River, with approximately 41,300 cubic meters per second. The high course of this river is called Lualaba.
Yangzi (6,380 km): The Yangtze River is the longest river in Asia and the third longest in the world, after the Nile and the Amazon. It is in China. The river is born on the Qinghai and Tibet Plateau, and flows eastward, crossing the provinces, autonomous regions and Chinese municipalities, landing in the East China Sea.
Mackenzie (river) (4,240 km): It is a Canadian river, 1738 km long, which, together with the rivers that flow into the Great Slave Lake, Peace and Finlay, form the second longest river system in North America. Its hydrographic basin covers 1,805,200 square kilometers and at its mouth it leaves 9,700 cubic meters of water at sea.
Obi (5,410 km): It is located in Western Siberia, Russia. Thus being the longest in the country and the second longest in Asia. It is born in the Altai Mountains (in Central Asia) at the confluence of the Biya and Katún rivers and flows into the Arctic Ocean, in the Gulf of Ob.
Mississippi River - Missouri
Mississippi River - Missouri (6,270 km): It is a United States river. It is the largest river system in North America. Its source is Lake Itasca, in Itasca Park in the northern part of Minnesota. The Mississippi goes through ten states of the United States: Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Arkansas, Tennessee, Mississippi and Louisiana. It flows into a large delta in the Gulf of Mexico approximately 160 km downstream from the city of New Orleans.
Nile (6,671 km): It has been historically considered the longest river in the world, however recent studies give this category to the Amazon River. It is located in northeast Africa. From its main source, Lake Victoria in central Africa, the Nile River flows to the Mediterranean Sea through Uganda, Sudan and Egypt.
Amazonas (7,020 km): It is a large South American river, and it is the longest river on the planet and it transports only one fifth of the planet's river water. Tour the largest humid tropical forest on the planet, distinguished by the generic name of Amazon or Amazon rainforest, one of the natural wonders of the world. The majority is concentrated in Brazil, but reaches Colombia, Bolivia and Peru.
