Explain the differences identified during the comparison (the Nile and the Amazon) and their reasons?

These are the two longest rivers in the world, but differ from each other primarily in terms of capacity and basin area. Hundreds of large and small rivers flow into the Amazon, as a result of which its basin is almost twice the size of the Nile. Also, the Amazon is more full-flowing and wider, ships can sail on it over 5000 km upward, and the Nile above 3200 km after the mouth is already narrow and not accessible for ships. This is because the Amazon flows through wetlands and the Nile through deserts and semi-deserts.
