A river refers to the flow of water flowing along a certain depression on the surface, which is divided into two categories: outflow rivers and inland rivers according to whether the river eventually flows into the ocean. The basic characteristics of rivers include two categories: hydrological characteristics and water system characteristics, hydrological characteristics mainly include annual runoff, seasonal changes in water level, freezing period, sediment content and flow rate, etc., and water system characteristics include river flow direction, flow, basin area, water system morphology and river characteristics.
The ten longest-flowing rivers in the world
The flow of a river usually refers to the length of the main stream of the river, that is, the length of the river from the source of the river to the mouth of the river (at the end of the river). The world's large and small rivers, the length of the process is different, so do you know which ten rivers in the world have the longest process? The ten longest-flowing rivers in the world are the Nile, Amazon, Yangtze, Mississippi, Yenisei, Yellow, Ob, Mekong, Paraná-La Plata and Congo.

Judging from the continental distribution of these ten rivers, five of them are located in Asia, namely the Yangtze River, Yenisei River, Yellow River, Ob River and Mekong River; two rivers are located in Africa, the Nile And Congo River; two rivers are located in South America, namely the Amazon River and the Parana River-La Plata River; and the Mississippi River is located in North America, while Europe, Oceania and Antarctica do not have rivers on the list.

The Nile River is located in northeast Africa, the upper reaches of the Nile River, the White Nile Originates in Burundi, the East African Plateau, the overall flow is from south to north, flowing through ten countries, and finally flows into the Mediterranean Sea in Egypt, the total length of the river is about 6670 kilometers, the longest river in the world, known as the Mother River by the Egyptian people. Located in the north of South America, the Amazon River is the largest runoff, the largest basin area and the largest number of tributaries in the world, flowing from west to east and joining the Atlantic Ocean, and the total length of the Amazon River is about 6440 kilometers, making it the second longest river in the world.
The Amazon and Paraná-La Plata
The Yangtze River is located in China in eastern Asia, originating in the Qinghai-Tibet Plateau region, and the overall flow direction is from west to east, and finally flows into the Pacific Ocean, which is the largest water system in China. The Yangtze River runs through China's three-step ladder from west to east, with a total length of about 6397 kilometers, which is the third longest river in the world and the longest river in Asia. Located in the south-central region of North America, the Mississippi River is a huge tree-like river system that flows from north to south and flows into the Gulf of Mexico, with a total length of about 6020 kilometers, making it the fourth longest river in the world.

Located in the Siberian region of Asia, the Yenisei River is the dividing line between the West Siberian Plain and the Central Siberian Plateau, and the overall flow direction is from south to north, eventually flowing into the Arctic Ocean. The Yenisei River is located in the middle and high latitudes, with a long ice period in winter, and multiple floods, with a total length of about 5539 kilometers, making it the fifth longest river in the world. The Yellow River is the mother river of China, originating from the Qinghai-Tibet Plateau, the river form shows a huge "several" shape, the Yellow River flows through the Loess Plateau region of China, and the river has a huge sediment content. The total length of the Yellow River is about 5464 kilometers, which is the sixth longest river in the world.
Yangtze and Yellow Rivers
Located in the Siberian region of Asia, the Ob River flows through the main topographical area of the West Siberian Plain, and the river flows from south to north and eventually flows into the Arctic Ocean. The source of the Ob River originates from the Altai Mountains, china's Irtysh River is a tributary of the Ob River, the total length of the Ob River is about 5410 kilometers, is the seventh longest river in the world. Located in the south of Asia, the Mekong River originates from the Qinghai-Tibet Plateau of China, called the Lancang River in China, and the overall flow direction is from north to south, and finally flows into the South China Sea in Vietnam. The Mekong River is an international river, flowing through a total of 6 countries, is the most important river on the Indochina Peninsula, the total length of the Mekong River is about 4909 kilometers, is the eighth longest river in the world.

The Paraná River - The Río de la Plata is located in the southeast of South America, the upper reaches are called the Paraná River, while the lower reaches are called the Río de la Plata, and the overall flow direction is from north to south, mainly through the Paraná Plateau and the Plain of La Plata. The Pampas, through which the lower reaches of the Paraná-La Plata River flows, is a world-famous cattle herding distribution area, with a total length of about 4880 kilometers, making it the ninth longest river in the world. Located in the Congo Basin in central Africa, the Congo River is located in the tropical rainforest climate zone, is a huge water system with many tributaries, flowing from east to west, and eventually into the Atlantic Ocean, the total length of the river is about 4700 kilometers, which is the tenth longest river in the world.
