What are the zones of altitudinal zonation?
Altitudinal zonation (or elevational zonation) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions.
What is the meaning of altitudinal zonation?
The pattern of variation of plant and animal species relative to elevation, in response to vertical differences in climate (particularly temperature and precipitation). From: altitudinal zonation in A Dictionary of Environment and Conservation »
How are life zones classified?
In 1947, Leslie Holdridge published a life zone classification using indicators of: mean annual biotemperature (logarithmic) annual precipitation (logarithmic) ratio of annual potential evapotranspiration to mean total annual precipitation.
What is an ecological life zone?
Merriam (1894) describing the way in which changing vegetation forms give a series of life-zones in relation to temperature gradients. In modern ecology these life-zones are defined by reference to a range of interacting environment gradients, and reflect animal as well as plant characteristics.
How does altitudinal zonation influence human activity What are the main altitudinal zones?
Human activity varies with elevation, and the activities can be categorized into zones according to altitudinal zonationVertical environmental zones that change with altitude in mountainous regions.. Each zone has its own type of vegetation and agricultural activity suited to the climate found at that elevation.
What is altitudinal zonation and why is it significant in Latin America?
So, for many Latin Americans, altitude has just as much influence on local temperature as latitude. Altitudinal zonation is the examination of how geographic traits change from lower elevations to higher elevations. Hot-weather crops, like bananas and sugar cane, thrive at these elevations in the tropics.
How does altitudinal zones influence human activity?

Which of the following is referred as the life zone?
zone of a biosphere reserve.
Which of the following is known to be the zone of life?
This generation of life in the thin outer layer of the geosphere established what is called the biosphere, the “zone of life,” an energy-diverting skin that uses the matter of Earth to make living substance.
What is altitudinal zonation quizlet?

What are the 5 life zones?
Which is the best description of altitudinal zonation?
Jump to navigation Jump to search. Altitudinal zonation (or elevational zonation) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions.
Which is a factor in the determination of vegetation zones?
Factors like temperature, soil composition, humidity, solar radiation, altitude, type of rocks, and disturbance frequency (like fire and monsoons) are responsible for the determination and occurrence of the zones. The zones are equipped to support several species of vegetation and animals.
How is the high alpine zone related to the temperate zone?
Plant species of the high alpine zones of the tropics, particularly in the southern hemisphere, are taxonomically related to the southern hemisphere temperate zone and antarctic floras. There are interesting convergences in lifeforms between the alpine flora of the Old World and New World tropics and, indeed, between some animal taxa, too.
What makes up the lower Sonoran life zone?
Lower Sonoran Life Zone. This vegetation of this life zone corresponds with the hot deserts of the southwestern United States and northwest Mexico (the Mojave, Sonoran, and Chihuahuan deserts). Creosotebush (Larrea tridentata) and other desert shrubs and succulents occur at elevations from 100 ft to 3,500-4,000 ft above sea level.
