The flowing water falls on the soft rock below, it wears it away and hard rock from the top of the water fall falls on the soft rock, as the hard rock falls from the top, it leaves a dent and the water wears this away, then pushing the waterfall back, wooop woopA waterfall is formed when there is a layer of hard rock and a layer of soft rock. The soft rock is eroded away first, so that the harder rock just hangs over, creating a waterfall.
