Ten Longest Rivers In The World

Ten Longest Rivers In The World

Rivers are the veins and arteries of our world. 

With water accounting for more than 70% of the earth's surface, it is no surprise that rivers and waterways play an important part in the lives of humans, animals, and ecosystems.

Freshwater rivers may be utilized for drinking, habitat, irrigation, transportation, and even for power generation. 

It is safe to say that rivers are a necessity that the world needs and preserving our rivers in the face of climate change is very important. 

These are the ten longest rivers and river systems in the world.


1. Nile River: 6,650 Km

The Nile is the world's longest river, stretching around 6,650 kilometres. 

It flows through various nations on the African continent, including Uganda, Ethiopia, Sudan, South Sudan, the Democratic Republic of the Congo, Kenya, Tanzania, Rwanda, Burundi, and Egypt. 

The Nile's principal tributaries are the Blue and White Niles, which feed into the river, which flows southward until emptying into the Mediterranean Sea. 

The Nile serves as an important source of water and transportation.

Its waters sustain nearly 40% of Kenya's population and are home to a variety of wildlife, including hippopotami, Nile crocodiles, and other creatures that rely on the river for freshwater.

2. Amazon River: 6,400 Km

The Amazon River is the world's second-longest river, stretching 6,400 kilometres. 

It is so near to the Nile in length that some statistics indicate it to be longer. 

It is also the world's biggest river in terms of volume or discharge volume. 

The Amazon is so enormous that two of the next two greatest rivers by volume are tributaries to it. 

The river flows through three South American countries: Brazil, Peru, and Colombia before emptying into the Atlantic Ocean. 

The Amazon rainforest, which surrounds the river, is recognized for being extraordinarily biodiverse. 

Many species may be found in the trees along the river's banks, but the waters are also teeming with life.

The Amazon area is home to almost one-third of all known species on the planet. 

Thousands of fish species, unique Amazon River dolphins, otters, manatees, and anacondas, as well as numerous other noteworthy reptile species, may be found in the river's waters.


3. Yangtze River: 6,300 Km

The Yangtze River in China is 6,300 kilometres long, making it the third-largest river in the world and the longest in Asia. 

The river travels east over much of China before draining into the East China Sea. 

The Yangtze River is a key water source in China, having a drainage basin that comprises nearly one-third of the country's population. 

Its banks are home to 400 million people. The river has historical significance and plays an important role in China. 

The river also serves as an unofficial boundary between North and South China. 

It has been used for drinking water, transportation, and irrigation and has been significant during wartime. 

Today, the Three Gorges Dam is the world’s largest power station, pulling power from the river.


4. Mississippi River: 6,270 Km

The Mississippi-Missouri River System runs 6270 kilometres through the southern United States. 

The Missouri and Mississippi Rivers are the two longest rivers in the United States, but because they flow into each other, they are sometimes referred to as one large river or river system. 

The Mississippi River has traditionally served as a key mode of transportation and is home to a diverse range of animals. 

The Mississippi Delta, in particular, contains a diverse range of environments, including Cyprus groves, marshes, and sandy beaches. 

These areas are home to a variety of animals and reptiles, including alligators, turtles, and a variety of fish species, as well as migrating and year-round waterfowl.


5. Yenisei – Angara – Selenga River: 5,500 Km

The Yenisei River is the world's fifth-longest river, stretching 5,550 kilometres. 

This system consists of multiple rivers that flow through Russia and Mongolia before draining into the Arctic Ocean. 

Despite its little depth, the river drains into Lake Baikal, the world's deepest and oldest lake. 

Many fish thrive in the Yenesei, and the banks provide important habitats for migrating reindeer, including the Aimyr herd, the world's biggest tundra reindeer. 

Unfortunately, it is thought that radioactive discharge from a covert bomb-making site has contaminated the river system.


6. Yellow River: 5,464 Km

The Yellow River, also known as the Huang He or Huang River, is the world's sixth-longest river and China's second-longest. 

It is roughly 5,464 kilometres long. From the western region of Qinghai to the Bohai Sea at Dongying, the river passes through nine distinct provinces in China. 

The Yellow River is historically significant since it was the site of early Chinese towns. 

The river has also been known to experience considerable floods, which have altered the river's flow over history. 

The river today has numerous important hydroelectric dams and power stations, as well as 160 different fish species.


7. Ob – Irtysh: 5,410 Km

The Ob River is approximately 5,410 kilometres long and flows across most of Russia before draining into the Arctic Ocean. 

Novosibirsk, Russia's third-largest city, is located along the river's banks, and the famed Trans-Siberian Railroad crosses the river here as well. 

The Ob is important to Russia and Siberia, both physically and economically. 

The river offers drinking water and agriculture as well as hydroelectric electricity through numerous power facilities such as Novosibirskaya GES. 

The river also contains more than 50 species of fish and is a major source of fishing for consumption


8. Río De La Plata: 4,880 Km

The Rio de la Plata is the world's eighth-longest river, stretching 4,880 kilometres. 

This river, which comprises the Parana and the Rio Grande, flows through Argentina and Uruguay. 

It is also the world's broadest river, opening into a bay-like region at its eastern end. 

Several significant cities, including Argentina's capital, are located along the river's banks. 

The river also contains many islands owned by Uruguay. Notably, the river is an estuary, receiving both fresh waters from the Parana and Uruguay rivers as well as saltwater from the salty ocean tides and currents. 

As a result, the river is home to several marine species, including green, loggerhead, and leatherback sea turtles, as well as the endangered Ls Plata dolphins. 


9. Congo River: 4,700 Km

The Congo or Zaire River is Africa's second-longest and second-largest river in terms of discharge volume. 

It is also the deepest known river, with a depth of up to 220 meters. 

The Congo River, which is made up of the Congo Lualaba and Chambeshi Rivers, is 4,700 kilometres long. 

The river travels across much of the Congo and twice crosses the equator before emptying into the Atlantic Ocean. 

The river has a seasonal flow of about 50,000 cubic meters, making it Africa's most powerful river. 

This energy is harnessed by 40 distinct hydropower facilities located across the Congo Basin.

10. Amur River: 4,444 Km

The Amur River is the world's tenth-longest, measuring around 4,444 kilometres. 

The river flows into the Sea of Okhotsk, the Pacific Ocean, and the Tartary Strait, forming a natural boundary between the Russian Far East and Northeastern China. 

The river is home to a diverse array of creatures, including the Amur softshell turtle and several fish species. 

Many of them are bigger predatory species, such as Amur pike, northern snakehead, and carp, as well as the enormous kaluga, which may grow to be over 5.5 meters long.
