Nile River

The longest river in Africa and one of the longest on Earth/Water

The Nile flows roughly 6,650 km from central Africa to the Mediterranean Sea, making it the longest or second longest river in the world depending on how you measure the Amazon. Ancient Egyptian civilization was built entirely around its annual floods, which deposited rich silt across the floodplain. The river passes through 11 countries and supports about 300 million people, making it arguably the most important waterway on the planet.
