Attrition – Erosion caused when rocks and boulders transported by waves bump in to each other and break in to smaller pieces

Attrition – think BUMP

A trick with attraction (attrition) is to make sure you bump into the person you are attracted to.

Attrition occurs when rocks and pebbles carried by waves smash into each other, and against the seabed and the base of a cliff or rocky outcrop.

Through this action, the rocks and pebbles are worn away, becoming smaller, rounder and smoother.
