Did you know? ...
Most rivers are tributaries, which means they join rivers before they reach the sea.

It is said that the River Thames used to be a tributary of the River Rhine. The Thames once flowed further to the north, through Buckinghamshire to Essex, before becoming a tributary to the River Rhine.  Around 475,000 years ago glaciers forced the river southwards along its present course.
