Step 1
Step 2
Explain how it was formed
Answer
A waterfall forms where a river flows over a layer of hard rock, with softer rock underneath. The persistent action of flowing water erodes the softer rock more quickly, leading to the creation of a drop, or waterfall. The processes involved include abrasion, where rocks and sediment carried by the water wear away the rock face, and hydraulic action, where water pressure forces air into cracks in the rock, causing further erosion.
