Morphology
stratigraphy = strata (semi-transparent) = strat + graphy
The term is a learned classical formation whose meaning is largely recoverable from the idea of 'layers' plus the suffix '-graphy' meaning a field of study or description.
Etymology
Stratigraphy comes from parts that mean 'layer' and 'writing': stratum (a 'layer') and -graphy ('writing' or 'record'), the same -graphy in geography. So, stratigraphy is like 'reading' the pages made by rock layers to learn Earth's history.
