Examples

  • The process of orogeny creates new mountain ranges as tectonic plates collide and push the Earth's crust upwards.

  • Quickly, the small white mountains began to dwindle as she rose, and the systematic faults of this orogeny presented themselves to her in detail.

Morphology

orogeny = oro + geny

The term is built from Greek combining forms 'oro-' (mountain) and '-geny' (birth/creation) which are not recognizable standalone English words, and the meaning is specialized technical vocabulary, so learners cannot reliably derive the sense from common English bases.

Etymology

The word orogeny comes from Greek parts oro- meaning 'mountain' and -geny meaning 'birth' or 'creation', like the gen- in generate and genesis. So, orogeny is the process of the 'birth' or building of mountains, which is why scientists use it for mountain formation.
