Waterfall
- Processes
- Hydraulic Action
- Abrasion
- Differential Erosion
- Undercutting
- Hydraulic Action
- Examples
- Powerscourt, Co. Wicklow
- Torc Waterfall, Co. Kerry
- Powerscourt, Co. Wicklow
- Formation
- An Interruption In The River Profile, The Water Makes A Vertical Drop
- Found In The Youthful Stage
- Where A Band Of Resistant Rock Lies Next To A Layer Of Less Resistant Rock
- The Waterfall Is Created Because Of Differential Erosion
- The River Erodes The Less Resistant Rock Faster Than The Less Resistant Through Hydraulic Action And Abrasion
- Less Resistant Rock = Eroded, Resistant Rock = Elevated
- Vertical Erosion Causes The River Channel To Deepen
- Water Becomes 'Broken' By The Development Of Rapids
- Over A Long Period, Less Resistant Rock Erodes, Producing A Vertical Drop, This Is The Waterfall
- Falling Waters Erodes Through An Eddying And Swirling Action, Developing A Plunge Pool
- The Plunge Pool Gets Deeper Through Further Hydraulic Action And Abrasion
- The Backwall is Further Eroded By Water Spray Eroding The Less Resistant Rock
- As The Less Resistant Rock Is Eroded, The Remaining Resistant Rock Is Left Further Exposed
- Eventually The Resistant Rock Falls In To The Waterfall
- The Erosion Of The Backwall Is Solution
- The Load Is Carried By The River Through Transportation
- An Interruption In The River Profile, The Water Makes A Vertical Drop
