Question Answer
What Is Hydraulic Action This is the sheer power of the water as it smashes against the river banks. Air becomes trapped in the cracks in the rock of the river bank and bed, and causes the rock to break apart.
What Is Abrasion? When pebbles grind along the river bank and bed in a sand-papering effect.
What Is Attrition? When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded.
What Is Solution? When the water dissolves certain types of rocks, eg limestone.
