That is how it works; originating from the heart of Africa, the Nile begins as two rivers: the White and the Blue Nile. The Blue Nile’s water may initially be blue, but it always turns brown/orange in colour. This happens because of the sand and soil in the river.
The White Nile looks a bit fresher than the Blue. Most of its water supply comes from rainfall. The White and the Blue Nile meet in the African country called Sudan. From there, they continue as a single river which eventually flows into the Mediterranean. The Nile, which is 6500 kilometres long, is the longest river in the world. As you can imagine, there are many magical stories about it, for example, the legends about unicorns. Impressive, right?
