Cliffs to Notches
Date: Fall 2013
How do cliffs become notches?
All large rock formations have cracks in them. Erosion takes advantage of pre existing cracks, sometimes called joints, to attack and remove the rock. The agents may be wind, water and or vegetation, but eventually erosion wins out.
Hope this helps.
I am not sure I understand your question.
If you are asking how cliffs get notched out, the answer is most usually water erosion.
