Im living next to the rhine river in Germany and while sitting next to it I started to wonder: why does it never stop, even though the water is always flowing in the same direction? Where does it come from? Where does it go? Where does it come from, river flow joe?

I’m going to share something with you that is so obvious, it blew my mind and I felt so stupid after realizing it.
Rivers flow because of gravity. That is right… rivers flow downhill. Land is ‘above sea level’, so inland rivers just flow downhill to empty into the sea.
So rain, snow… falls on land and fills up lakes and other water bodies. Water from these drain into rivers and eventually out to the ocean due to simple gravity.
Maybe you already knew that, but it explains so much.
