The wearing away and breaking up of rock along the coast.
Air may become trapped in joints and cracks on a cliff face. When a wave breaks, trapped air is compressed which weakens the cliff and causes erosion.
Bits of rock and sand in waves grind down cliff surfaces like sandpaper.
Waves crash rocks and pebbles on the shore into each other, and they break and become smoother.
Acids contained in sea water will dissolve some types of rocks such as chalk or limestone.
