      I suppose it’s all because of gravity. Rain falls on hills and gravity makes it run downhill to join up with other drops of water and become a stream. Streams join together to make rivers that get bigger and bigger until they reach the sea. Different rivers flow at different speeds depending how steep the land is and because of other things such as how straight they are and how smooth the river bed is.

      If there was no gravity there’d be an awful lot of lakes going nowhere….
