Morphology
petrologist = petrology (semi-transparent) = petro + log + ist
The word is transparently formed from the technical base 'petrology' plus '-ist', but the specialized scientific meaning is not fully obvious to average learners.
Etymology
The word petrologist comes from Greek parts petro- meaning 'rock', the same root you see in petrol and petroleum, and -logist meaning 'one who studies', like in biologist. So a petrologist is a scientist who studies rocks and how they formed.
