chemical weathering
breakdown of rock changing its chemical composition
2 of 7
mass movement
shifting of rock and loose material down a slope. it happens when the force of gravity is stronger than the force supporting it.
3 of 7
hydraulic power
waves crash against the rock and compresses the air into cracks. this puts pressure on the rock. repeated compression widens the cracks and makes bits of rocks break off.
4 of 7
abrasion
eroded particles in the water scrape and rub against rock, removing small pieces.
5 of 7
attrition
eroded particles in the water smash into each other and break into smaller fragmnts. their edges also get rounded off as they rub together.
6 of 7
solution
weak carbonc acid in seawater dissolves rock like chalk and limestone.
