Morphology
geochronology = chronology (semi-transparent) = geo + chron + logy
The word builds on the recognizable base 'chronology' with 'geo-' added, but the resulting scientific term is specialized and not fully predictable for an average learner.
Etymology
The word geochronology comes from geo- ('Earth'), chron- ('time') and -logy ('study'), and you can see geo- in geology and chron- in chronicle. So, geochronology is the study of Earth's 'time', how scientists tell the age and order of events in Earth's history.
