A System of Natural Areal Complexes of the Earth

The tiered vertical structure of all the earth's landscapes is used as the basis for a typological classification of all natural areal complexes. Four basic landscape divisions are proposed: (1) terrestrial landscapes, consisting of an upper aerial layer and lower mineral layer, (2) aquatic landscapes, consisting of three tiers: air, water, mineral base, (3) glacial landscapes, consisting of three tiers (air, ice, mineral) on land, and of four tiers (air, ice, water, mineral) in oceans, (4) variable landscapes distinguished by a periodic succession of structures (terrestrial-aquatic, terrestrial-glacial, aquatic-glacial).
