Definition:
The science dealing with the form and surface configuration of the solid earth.
It is primarily an attempt to reveal the complex interrelationships between the
origin (and therefore material composition) of surface features on the one
hand, and the causes of the surface alteration (erosion, weather, crustal
upheaval, etc.) on the other hand.
