Answer: Option A
Answer: (a)
In physical geography, the tundra is a biome where tree growth is hindered by low temperatures and short growing seasons.
There are three types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra where the subsoil is permafrost or permanently frozen soil.
Rainfall and snowfall are generally slight due to the low vapour pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes.
