Surface Forms

subsurface positive

Morphology

subsurface = surface (transparent) = sub + surface

The meaning is directly derivable from the prefix 'sub-' (under) plus 'surface' (outer layer), yielding 'beneath the surface'.

Etymology

Subsurface is made of the prefix sub- meaning 'under' and the word surface meaning 'the top layer' or 'outside', just like in submarine where sub- also means 'under'. So subsurface means something that lies 'under' the surface, for example layers of rock or ice below the ground.
