Cards in this deck (4)
- 1What Is Hydraulic ActionThis 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.
- 2What Is Abrasion?When pebbles grind along the river bank and bed in a sand-papering effect.
- 3What Is Attrition?When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded.
- 4What Is Solution?When the water dissolves certain types of rocks, eg limestone.
