tree cannot grow or survive beyond the artic Circle in Asia. Why?
Answers
Tree line above St. Moritz, Switzerland. May 2009
In this view of an alpine tree line, the distant line looks particularly sharp. The foreground shows the transition from trees to no trees. These trees are stunted in growth and one-sided because of cold and constant wind.
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions (usually cold temperatures or associated lack of available moisture).[1]:51 The tree line is sometimes distinguished from a lower timberline or forest line, which is the line where trees form a forest with a closed canopy.[2]:151[3]:18
At the tree line, tree growth is often sparse, stunted, and deformed by wind and cold krummholz (German for "crooked wood").[4]:58
The tree line often appears well-defined, but it can be a more gradual transition. Trees grow shorter and often at lower densities as they approach tree line, above which they cease to exist.[4]:55
Answer:
Answer:-
Trees or forests cannot grow or survive in the regions beyond the Arctic Circle in Asia because this region has long severe winters and the frozen subsoil which do not permit the growth of trees and this region is, therefore, devoid of forests.
