Altitudinal zonation

Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere).[4]

Altitudinal Zonation of Grand Teton in the Rocky Mountains (note change in vegetation as altitude increases)

Altitudinal Zones of Andes Mountains and Corresponding Communities of Agriculture and Livestock Raised

Altitudinal zonation in mountainous regions describes the natural layering of ecosystems that occurs at distinct altitudes due to varying environmental conditions. Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, which consequently support different vegetation and animal species. Altitudinal zonation was first hypothesized by geographer Alexander von Humboldt who noticed that temperature drops with increasing elevation. Zonation also occurs in intertidal and marine environments, as well as on shorelines and in wetlands. Scientist C. Hart Merriam observed that changes in vegetation and animals in altitudinal zones map onto changes expected with increased latitude in his concept of life zones.
