- 1. Waterfalls
- 2. How They Form. Waterfalls form when melt water drops over
theedge of a tabular iceberg or ice self. Waterfalls are commonly
formed when a river isyoung. As the watercourse increases its
velocity at the edgeof the waterfall, it takes material from the
riverbed. Often over time, the waterfall will recede back toform a
gorge downstream as it recedes upstream,and it will carve deeper
into the ridge above it.
- 3. What w erf al l s do. atdo Waterfalls picks up rocks from
the ground and dropsthem at the bottom of the waterfall and then
that formsa fan. They also cause death for people, because
sometimespeople slip or fall down the waterfall and when they
fallthey die at the bottom. Waterfalls are like sandpaper to the
base (floor). Theyscrape off the layer of for example rock. Very
slowly thewater (rushing down from the top of the waterfall)scrapes
off the base of the rock. The base gets smallerand smaller until
there is nothing left.
