Morphology

outcrop = crop (semi-transparent) = out + crop

The verb is analyzable as 'out' + 'crop' (to come out/appear), but relies on a less common sense of 'crop' so learners may not fully infer the meaning. [Postprocessing: moved 'out' from base_words to prefix]

Etymology

Outcrop as a verb comes from the idea of something 'cropping out' or 'coming out' of the earth, so to outcrop is for rock or layers to 'become visible' at the ground surface.
