Orography is the study of the topographic relief of mountains, and can more broadly include hills, water stream directions and any part of a region's elevated terrain. Orography (also known as oreography, orology, or oreology) falls within the broader discipline of geomorphology. The term orography comes from the Greek: , hill, , to write.
