The Arctic Circle
The parallel of latitude that circumscribes the polar tundra zone is the Arctic Circle in the northern hemisphere and the Antarctic Circle in the southern hemisphere. These circles mark the boundary where the tundra biome transitions into the polar ice caps.
The parallel latitude that circumscribes the polar tundra zone is the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere. These latitudes mark the boundaries of the tundra biome, characterized by cold temperatures and a lack of trees due to permafrost.
It is the Arctic Circle and it is approximately 66 degrees north of the equator.
The parallel line of latitude that circumscribes the polar tundra zone is the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere. These circles mark the approximate southern and northern boundaries of the tundra biome where the cold climate and limited vegetation characteristic of tundra regions are found.
Very far south. It is cold and so then the latitude will probably be negative. If you thought it would be positive, you are crazy.
There are several other names for high latitude areas of the world. There is the Arctic/Antarctic, tundra/taiga, and several other things.
An Alpine Tundra has permafrost however, Alpine Tundra is found at the tops of tall mountains. Polar Tundra is found near the North and South Poles. The alpine tundra is found at any latitude. Polar tundra has snow covering its surface. The alpine tundra has grass covering its surface. The alpine tundra also has delicate plants that take 4-5 years to flower. One piece of trash could kill a flower that is decades old in just a few weeks.
Being a polar or high latitude climate, the tundra is noted for its low temperature. The tundra is basically summer-less, having no monthly temperature averaging above 10o C, and having at least nine months below freezing.
Tundra biomes generally occur near the Arctic Circle, between 60° to 75° latitude in the northern hemisphere. In the southern hemisphere, tundra biomes are found near the Antarctic Circle, between 60° to 75° latitude.
The word 'polar' defines the latitude. Should the latitude change it would no longer be polar.
