The Nile River, recognized as the world’s longest river, originates deep within Africa. This majestic river flows northward from near the Equator and empties into the Mediterranean Sea just north of Cairo, Egypt. Though the Amazon River in South America is slightly shorter, it boasts a significantly higher volume of water, making it enormously wide in certain areas—so wide, in fact, that one cannot see either riverbank. In contrast, as depicted in the accompanying images, the Nile River in Cairo appears considerably narrower, especially near the delta where it meets the Mediterranean.
