Morphology

planation = plane (semi-transparent) = plan + ation

Morphologically it is 'plane' + '-ation' meaning the process of making flat, but the form appears as 'plan-' and the term is technical and not broadly familiar.

Etymology

The word planation comes from the Latin root planus, which means 'flat', and is like plane (a flat surface) or plain (flat land) to help you remember it. So planation is the slow wearing away of rock or soil that makes a nearly level, flat surface.
