Morphology

isobase = base (semi-transparent) = iso + base

The prefix 'iso-' indicates equality, but the specific application to land uplift is specialized.

Etymology

The word isobase comes from the Greek part iso- meaning 'equal' and the word basis meaning 'base' or 'level'. Like the lines on a weather map that show equal pressure or temperature, an isobase joins places that rose by the same amount.
