orography, oreography|ɒˈrɒgrəfɪ, ɒrɪˈɒg-|
[f. Gr. ὄρος, ὄρε- mountain + -graphy. Greek compounds of ὄρος are formed in ὀρει-, ὀρο-, and ὀρε(ο-; hence the two forms, of which orography is now the more usual. So in Fr., orographie (Dict. Acad. 1878) has displaced oréographie.]
That branch of physical geography which deals with the formation and features of mountains; the description of mountains. Also, the orographical features of a region.
