Definition box

Where rock pieces move against another rock and wear it away, e.g. a pebble is washed against a cliff by waves and breaks off tiny bits of the cliff. If you rub two pebbles together you will have abrasion and the pebbles will begin to be worn away. You can try it with two pieces of chalk. Abrasion will cause them to crumble to powder.
