  2. Organisms at high altitude - Wikipedia

    en.wikipedia.org/wiki/Organisms_at_high_altitude

    Trees cannot grow at high altitude, because of cold temperature or lack of available moisture. [82]: 51 The lack of trees causes an ecotone, or boundary, that is obvious to observers. This boundary is known as the tree line. The highest-altitude plant species is a moss that grows at 6,480 m (21,260 ft) on Mount Everest. [83]

    Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.

    Here, h signifies low-latitude climates (average annual temperature above 18 °C (64.4 °F)) while k signifies middle-latitude climates (average annual temperature less than 18 °C). In addition, n is used to denote a climate characterized by frequent fog and H for high altitudes.

    This is known as an adiabatic process, which has a characteristic pressure-temperature curve. As the pressure gets lower, the temperature decreases. The rate of decrease of temperature with elevation is known as the adiabatic lapse rate, which is approximately 9.8 °C per kilometer (or 5.4 °F per 1000 feet) of altitude. [6]
