Trivia: Which of these Central Asian rivers is the longest?
Tarim River
Naryn River
Chu River
Syr Darya
The correct answer is Syr Darya
So why is this answer correct? : The Amu Darya contains the greatest amount of water of any river in Central Asia, but the Syr Darya flows for 1,374 miles, making it the longest. The Syr Darya is formed by the confluence of the Naryn River and the Qoradaryo River. The Irtysh River, which crosses through Central Asia, is even longer, but it begins in Russia and ends in China.
