What causes a waterfall to form?

Answer 1

JESUS

Answer 2

Stating the obvious: Water flows downhill. As long as rain continues to fall above the waterfall then it will continue to flow. I saw a waterfall in Scotland a few summers ago (Reekie Linn in Angus) which was in a very dry summer, it looked very tame, but no doubt that in time of high rainfall it will flow with all its considerable vigour. No, there is no reason to suggest a waterfall will not continue to be a spectacular sight.

Answer 3

Because there is a constant supply of water (usually melted from a glacier high in the mountains) upstream at the head water. In the spring snow melts and things contribute to the higher amount and flow of water, in the summer and fall, the source will be melted to a point where it will need to be built up again. By then winter hits, and the nows come in, cover the mountains and add to the glaciers.

Answer 4

Waterfall is the term for a gravitational fall of water in a river. (water fall.) It forms quite the same way as canyons: The river carves through the berg or what ever, but at one point the ground is weaker, causing the river to carve faster. Making a rapid change of elevation. Water fall s down at that point.

Answer 5

A waterfall forms when a river flows over a steep drop or cliff in its path, causing the water to cascade downward. This usually occurs as a result of erosion, where the force of the water wears away the rock or soil beneath it over time, creating a vertical drop.
