The Longest Rivers in the World


Did you know that the longest river in the world is the Nile? Egypt's greatest river is 4,135 miles long! In fact, Africa has two of the ten longest rivers. The Congo, which flows through central Africa, is Number 8 at 2,914 miles long.

What's the second longest river? Why, the Amazon, of course! It is about 4,000 miles (3,980, really) from start to finish, winding its way through most of South America.

China lays claim to Numbers 3 and 6: The Yangtze River is 3,917 miles long, and the Huang He is 3,395. North America's longest river, the Mississippi and Missouri combination, comes in at 3,870 miles long.

How do we measure these rivers? Geographers calculate the distance from the source of the river to its mouth. For instance, the Ob-Irtysh River, which is Number 7 on the list, is 3,354 miles long from its source in southern Russia to its mouth in the Ob Bay, in the very cold waters off northern Russia.

Russia has three more rivers in the Top Ten. Number 5 is the Yenisie River, which flows through Siberia and is 3,440 miles long. The Amur River runs through northeast Asia and totals 2,744 miles in length. The Lena River, at Number 10, flows north through central Russia and is 2,728 miles long.




Longest River of India

Ganga is the longest river of India. The total length of the Ganga river from its source to its mouth (measured along the Hughli) is 2525 km of which 1450 km is in the Uttar Pradesh, 445 km in Bihar and 520 km in West Bengal. The remaining 110 km stretch of the Ganga forms the boundary between Uttar Pradesh and Bihar.

The Ganga originates as Bhagirathi from the Gangotri glacier in Uttar Kashi District. It is joined by the Alaknanda at Devaprayag and the combined flow of the Bhagirathi and the Alaknanda is known as Ganga. After traveling 280 km from its source, Ganga enters plains at Haridwar. At Allahabad, about 770 km south-east of Haridwar, Ganga is joined by Yamuna, which is its most important tributary. After Farraka in West Bengal, the river ceases to be known as the Ganga. It bifurcates itself into Bhagirathi-Hughli in West Bengal and Padma-Meghna in Bangladesh. After traversing 220 km further down in Bangladesh, the Brahmaputra joins it at Goalundo and after meeting Meghna 100 km downstream the Ganga joins the Bay of Bengal.
