Waterfall Connotations

Waterfalls are places in a river where the water rapidly descends as it flows over a steep region or cliff. Waterfalls are usually created when a river is young at these times they are narrow and deep. When the river comes across a hard rock when they come to a softer one which erodes at a quicker rate (this is called differential erosion), so while the hard rock may stay the same structure more time than the softer one which gets eroded. This meaning



there is an overhang with a plungpool. The soft rock keeps getting eroded by undercutting it is eroded enough for the hard rock to collapse. So overtime the waterfall goes backwards up the river or spring.
