Top 10 Longest Rivers in the World
Here we have provided the longest rivers in the world list along with the top 10 longer rivers. This list of the top 10 longest rivers in the world will enhance your preparation process for your upcoming exams.
1. Nile River
The Nile River is thought to be the world's longest river. The Nile River spans 6650 kilometers in total.
-
The river is thought to have its origins in Lake Victoria.
-
Egypt, Uganda, Ethiopia, Kenya, Tanzania, Rwanda, the Democratic Republic of the Congo, Eritrea, Burundi, Sudan, and South Sudan are among the countries through which it flows.
-
The two tributaries of the river are the Blue and White Niles.
-
Although the Nile River may be the longest in the world, according to the majority of people, other scholars believe the Amazon River is the genuine winner of this distinction.
-
Multiple sources and numerous tributaries, both big and minor, can be found in major rivers like the Nile and Amazon.
-
If the actual length of a river needs to be determined, the furthest source must be located.
-
Such sources are frequently hidden away in difficult-to-reach places, making it difficult to find them.
-
What is the longest river in the world? The answer is the Nile, with a span of 6650 kilometers in total.
2. The Amazon River
Without a doubt, the Amazon River is the greatest in the world in terms of water discharge.
-
The Nile River in Egypt has long held the title of the longest river in the world, hence, its place as the second-longest river in the world is hotly contested.
-
Determining Amazon's origin is the source of the controversy.
-
The Cordillera Rumi Cruz, according to a 2014 study, is where the Amazon had its start.
3. The Yangtze River
The Yangtze River is the third longest river in the world and the longest to flow wholly within a single nation.
-
Additionally, it is Asia's longest river. One-third of the people who live in China, the nation with the highest population in the world, reside in the Yangtze River basin.
-
The Tanggula Mountains' Tuotuo tributary is traditionally acknowledged by the Chinese government as the river's source.
-
However, new information indicates that the Yangtze River's source is near Jari Hill, where the Dam Qu tributary's headwaters begin.
-
These and other tributaries combine to produce the powerful Yangtze River, which empties into the East China Sea in Shanghai.
4. The Mississippi River
The Mississippi, Missouri, and Jefferson rivers together make up the fourth-longest river system in the world.
-
The river system drains two Canadian provinces as well as 31 US states.
-
The source of the Mississippi River is said to be Lake Itasca in northern Minnesota, and it rises there before emptying into the Gulf of Mexico.
-
But if we consider the Jefferson River to be the Mississippi River's furthest source, we get the Mississippi-Missouri-Jefferson River system.
5. The Yenisei River
The river system that empties into the Arctic Ocean is the largest and fifth-longest in the world.
-
This river system's headwaters are thought to be the Selenge River.
-
The 992 km Selenge River empties into Lake Baikal.
-
The Russian Irkutsk Oblast is where the Angara River originates from Lake Baikal near Listvyanka before joining the Yenisei River close to Strelka.
-
Finally, the Yenisei empties into the Arctic Ocean. 5,539 miles are covered in total.
6. The Yellow River
-
This enormous river, also known as the Huang He, is also known as the Yellow River due to the color it has, which is the result of enormous volumes of loose silt in the water.
-
Its basin is regarded as the birthplace of ancient Chinese civilization and continues to have significant symbolic and economic relevance for the nation.
7. The Ob-Irtysh River
-
Along with the Yenisei and the Lena, the Ob-Irtysh, commonly referred to as the Ob River, is one of the three major rivers that flow through Siberia.
-
The Arctic Ocean is where it empties after flowing from the Atlas Mountains.
8. The Parana River
-
The Parana River, which flows through South America, is the second-largest river on the continent and one of the longest rivers in the world.
-
Its name is an acronym for the Tupi phrase para rehe onáva, which means "like the sea" in English.
9. The Congo River
-
The Congo, formerly known as the Zaire River, curves across Africa and holds the distinction of being the only river to cross the equator twice.
-
With some locations reaching depths of over 700 feet, it is also the world's deepest river.
10. The Amur River
-
The Amur River, also known as the Heilong Jiang, runs along the border between northeastern China and Russia and is the tenth-longest river in the world.
-
The Chinese word Heilong Jiang translates to "black dragon river," even though the word Amur is supposed to have come from a word meaning "water."
