The river’s tributaries extend the main river and measuring it is challenging since it includes several sub-rivers. Asia is consists of several large nations with spectacular landscapes, high altitudes, and cold climates. The lengths of the majority of the rivers given are merely estimations, and the longest rivers are still a source of contention. The major sources of Asia’s rivers are the icy mountains, rainfall, and streams. Thousands of rivers pour into the ocean, the majority of which originate in Asian countries such as India, China, and Russia. The Yangtze is Asia’s longest river, with a length of 6,300 km and a drainage area of around 1.8 km² before joining the Yellow River.
