1 Why are all trees absent in the polar regions?

Answers

Answered by mani060411

Answer:

Under a thin soil layer exists permanently frozen ground, or permafrost. The existence of contiguous permafrost is thought to be one of the main reasons why there are no trees in the tundra, because, being permenantly frozen, permafrost has a tendency to hamper root development.
