A river is a naturally flowing watercourse, generally of freshwater, that flows into an ocean, sea, lake, or another river. Rivers transport water and nutrients all across the world. They are vital to the water cycle because they serve as drainage pathways for surface water. Rivers drain roughly 75% of the world’s land surface.
Many of the earth’s creatures find ideal home and nourishment in rivers. Rivers provide a diverse range of unusual plants and trees. Ducks, voles, otters, and beavers live on the river’s banks. Along the riverbanks, reeds and other vegetation such as bulrushes flourish. Other animals feed and drink from the river. Small fish from the river are eaten by birds such as kingfishers. Many wild animals depend river for water. Many different types of fauna may be found in river deltas. The delta serves both a habitat and a food source for insects, animals, and birds.
Fertile soils can be found in river valleys and plains. Farmers in arid areas irrigate their crops with water brought by irrigation canals from neighbouring rivers. Rivers are a major energy source. Mills, shops, and factories were erected alongside fast-flowing rivers so that water could be utilised to power equipment throughout the early industrial age. Even today, steep rivers are utilised to power hydroelectric facilities and water turbines.
1. Nile River
The Nile River is the world’s longest river which flows around 6650 kilometres across many countries. Lake Victoria is famed as to be the river’s headwaters. It flows across Egypt, Uganda, Ethiopia, Kenya, Tanzania, Rwanda, the Democratic Republic of the Congo, Eritrea, Burundi, Sudan, and South Sudan before reaching the Red Sea. Although the Nile River is the longest river in the world for most of us, some academics believe the Amazon River is the genuine winner of this distinction. Big rivers, such as the Nile and the Amazon, have several origins as well as numerous large and minor tributaries.
2. The Amazon River
The Amazon River is without a doubt the world’s greatest river in terms of the volume of water. The length of this river comes around 6575 k.m. However, its claim as the world’s second-longest river is fiercely contested, as the distinction has long been held by Egypt’s Nile River. The disagreement stems from the determination of the Amazon’s genesis. According to a 2014 research, the Amazon’s origins may be traced back to the Cordillera Rumi Cruz.
3. The Yangtze River
The Yangtze River is the world’s third-longest river and the world’s longest river that flows wholly within one nation. It is 6300 Kms long and also Asia’s longest river. A large population of the world’s most populous country, China, lives in the Yangtze River basin. The Tuotuo tributary in the Tanggula Mountains has traditionally been recognised as the river’s source by the Chinese government. According to fresh research, the Yangtze River’s source is situated in the Jari Hill, where the headwaters of the Dam Qu tributary begin. These and other tributaries combine to produce the enormous Yangtze River, which eventually empties into the East China Sea near Shanghai.
4. The Mississippi River
The Mississippi, Missouri, and Jefferson rivers form the world’s fourth longest river system. The length of this river is 6275Kms. The river system drains 31 US states and two Canadian provinces. The Mississippi River originates in northern Minnesota, where Lake Itasca is said to be the river’s source, and flows into the Gulf of Mexico. However, if we consider the Jefferson River to be the Mississippi River’s farthest source, we obtain the Mississippi–Missouri–Jefferson river system.
5. The Yenisei River
This is the world’s fifth-longest river system, as well as the biggest to drain into the Arctic Ocean. The Selenge River is considered the system’s headwaters. The Selenge River is 992 kilometres long and it flows in to Lake Baikal. The Angara River begins near Listvyanka in Lake Baikal and runs through Russia’s Irkutsk Oblast before joining the Yenisei River near Strelka. Finally, the Yenisei runs into the Arctic Ocean. The total distance travelled is 5,539 miles.
6. The Yellow River
This gigantic river, also known as the Huang He, is known as the Yellow River because of its hue, which is the consequence of massive volumes of loose silt in the water. The length of this river is 5464 Kms. Its basin is regarded as the cradle of ancient Chinese civilisation, and it continues to be of significant importance to the country, both practically and symbolically.
7. The Ob-Irtysh River
Along with the Lena and the Yenisei, the Ob-Irtysh, often known as the Ob River, is one of the three main Siberian rivers. It flows from the Altas Mountains into the Arctic Ocean and it has 5410 Kms length.
8. The Parana River
The Parana River which is located in the South America is one of the world’s longest rivers and the continent’s second-largest. The length of this river is 4880 Kms. Its name is an acronym of the Tupi phrase para rehe onava, which means “like the sea.”
9. The Congo River
The Congo River, formerly known as the Zaire River, flows in a curved pattern through Africa and is the only river to cross the equator twice. It is also the world’s deepest river, reaching depths of over 700 feet in certain spots. The Congo river is 4700 Kms longer.
10. The Amur River
The Amur River, also known as the Heilong Jiang, is the world’s tenth longest river, stretching along the boundary between northeastern China and Russia. While the name “amur” is supposed to be derived from a phrase for “water,” the Chinese Heilong Jiang translates to “black dragon river.” This river has 4480 Kms length.
