Phyto geographical Division of Earth's Surface Exploration
This exploration delves into the phyto geographical division of the Earth's surface, examining vegetation zones, plant areas, and regional phyto geography. It discusses areas like Holarctic, Palaeotropical, Neotropical, Australian, Cape, and Antarctic. The content covers the belt of tropical rainforests, deciduous and semi-deciduous forests, savannah belt, and deserts. It explains the distribution of vegetation based on altitudinal zonation and latitude, showcasing the diverse flora in different phytogeographical areas.

VEGETATION OF THE EARTH IS DIVIDED: horizontally plant areas and vegetation zones vertically altitudinal zonation elevation levels
REGIONAL PHYTOGEOGRAPHY examines the various flora phytogeographical areas
PLANT AREAS the highest phytogeographical units divided into sub-regions, provinces
AREAS Holarctic Palaeotropical Neotropical Australian Cape Antarctic
VEGETATION ZONATION an inevitable extension of vegetation depending on latitude from the equator to the poles we can see coherent and parallelly organized VEGETATION ZONES
THE BELT OF TROPICAL RAINFORESTS equatorial regions balanced climate, the average temperature 24- 29 C even abundant rainfalls diverse vegetation, dominated by trees
THE BELT OF DECIDUOUS AND SEMI- DECIDUOUS FORESTS it follows the tropical rain forests on the southern and northern hemisphere temperature differences between the cold season and the warm season irregular rainfalls
THE SAVANNAH BELT tropical and subtropical areas of the southern hemisphere the rainy season 2-4 months the tall grass vegetation, sparsely scattered shrubs or trees
THE BELT OF DESERTS AND SEMI-DESERTS in the tropics, subtropics and temperate regions a small amount of precipitation large temperature differences between day and night very sparse vegetation
THE BELT OF FOREST WITH HARD LEAVES AND THEIR ALTERNATIVE COMMUNITIES. areas with maximum precipitation in winter and very dry and warm summers (eg. California, Mediterranean) original vegetation - evergreen forests current vegetation - scrub communities
THE BELT OF DECIDUOUS BROAD-LEAVED FORESTS. temperate zones of the northern hemisphere winter lasts 3-4 months deciduous trees
THE BELT OF STEPPES in extratropical areas little rain vegetation - grasses, herbs The Central Asia, Ukraine, North America (prairie), South America (pampas)
THE NORTHERN BELT OF CONIFEROUS FORESTS Northern Europe, Asia, North America characterized by large fluctuations in temperature spruce, pine, fir, larch northern boundary of the forest
THE BELT OF TUNDRA a northern hemisphere a short growing season and low summer temperatures mosses, lichens, shrubby birches, willows
WORKSHEET - REVISION How to divide vegetation on Earth? What does regional phytogeography study? What are the plant areas? Which plant areas do we know and what is characteristic for each of them ?
