How does water reach the top of the waterfall?

It is beacause water from rivers , lakes, seas and other main water recources would flow down a waterfall. Since water cycle takes place all the time,water that has flown down the waterfall would be evaporated and creating water vapour.water vapour rises high in the cold sky , thus water vapour would condense to form clouds.When the cloud gets heavy it realises water and creates rain.rain would land on rivers ,lakes , seas and othe main water recources and the cycle continues.
