Morphology
transgression = transgress (semi-transparent) = transgress + ion
The geological sense is a specialized, technical extension of 'to go across' (the sea moving over land); the morphological relation is clear but the meaning is domain-specific and metaphorical.
Etymology
In geology, transgression also comes from Latin trans- 'across' and -gress 'step', so imagine the sea 'stepping across' the land and covering it. That picture helps explain why geologists call the sea moving inland and leaving marine layers over land a transgression.
