Waterfall
1 Processes
1.1 Hydraulic Action
1.2 Abrasion
1.3 Differential Erosion
1.4 Undercutting
2 Examples
2.1 Powerscourt, Co. Wicklow
2.2 Torc Waterfall, Co. Kerry
3 Formation
3.1 An Interruption In The River Profile, The Water Makes A Vertical Drop
3.2 Found In The Youthful Stage
3.3 Where A Band Of Resistant Rock Lies Next To A Layer Of Less Resistant Rock
3.4 The Waterfall Is Created Because Of Differential Erosion
3.5 The River Erodes The Less Resistant Rock Faster Than The Less Resistant Through Hydraulic Action And Abrasion
3.6 Less Resistant Rock = Eroded, Resistant Rock = Elevated
3.7 Vertical Erosion Causes The River Channel To Deepen
3.8 Water Becomes 'Broken' By The Development Of Rapids
3.9 Over A Long Period, Less Resistant Rock Erodes, Producing A Vertical Drop, This Is The Waterfall
3.10 Falling Waters Erodes Through An Eddying And Swirling Action, Developing A Plunge Pool
3.11 The Plunge Pool Gets Deeper Through Further Hydraulic Action And Abrasion
3.12 The Backwall is Further Eroded By Water Spray Eroding The Less Resistant Rock
3.13 As The Less Resistant Rock Is Eroded, The Remaining Resistant Rock Is Left Further Exposed
3.14 Eventually The Resistant Rock Falls In To The Waterfall
3.15 The Erosion Of The Backwall Is Solution
3.16 The Load Is Carried By The River Through Transportation
