Rivers have played a crucial role in shaping civilizations, fostering trade, and sustaining ecosystems. Understanding the world's longest rivers not only enhances our knowledge of geography but also underscores their importance to humanity and the environment. Below, we present a comprehensive list of the 10 longest rivers in the world, detailing their origins, lengths, and significance.
1. Nile River
The Nile River, often regarded as the cradle of civilization, stretches approximately 6,650 kilometers across northeastern Africa.
