How does the waterfall works? Where does the water comes from?

Answer 1

A river or stream is going along, and the ground level gets lower and lower... suddenly, there is a cliff, and the river water falls down the cliff. That is what makes a waterfall!

(Actually it happens over hundreds / thousands of years, but that's the basic premise.)

Answer 2

A waterfall is nothing more than a sudden drop in a river. The answer to where the water comes from, then, is the origin of the river. Sometimes it is a spring, sometimes a lake, sometimes melt water from snows, and so on. Whatever feeds the river that jumps over the falls is the source of the falling water.

Answer 3

Well the waterfall is acutally once part of the river also known as a river feature.The water fall has two layers , the upper layer is made of hard rock and the bottom soft rock . Over thousands /millions/ hundreds of years the fast flowing river water washes away the soft rock underneath forming a cliff , that's known as a waterfall =)

Answer 4

The water comes from the clouds usually in the form of rain or snow. It falls on high ground and flows to sea level. Usually difference in elevation is gradual. When the elevation difference is immediate and great, the water falls to the lower level.

Answer 5

first of all th water flows downwards, either from a natural stream or from rain/snow runoff.
then when it encounters a drop th water erodes th drop further, then as it gets a longer drop it becomes a waterfall.
