crustal
Relating to tectonics
Crustal relates to a crust—most often Earth's outer rocky layer.
Geologists study crustal movement, crustal thickness, and crustal plates.
The term appears in discussions of earthquakes, tectonics, and planetary science: Crustal deformation occurs along fault lines.
Less commonly, crustal can describe any hard outer coating, as on bread or wounds.
