In nature, there are repeating patterns, whether it's the shapes of the continents or the flow of a river. And when it comes to landscapes, it's no different.

The Earth is an immense landmass that is surrounded by water on all sides, making it utterly unique. Rivers are the main way continents and islands are connected, and the water responsible for this vast process is what we call a river basin.

The largest river basins on Earth include the Amazon, the Congo, and the Nile, to name just a few.
