One unique characteristic of the Arctic tundra is permafrost--ground that is permanently frozen. Because the permafrost has no cracks or pores, nothing can penetrate it--neither plant roots nor water. The surface layer above the permafrost thaws each summer. This layer is called the active layer.

Answer:

Tundra biomes

Explanation:

  • Tundra biomes are known for their permafrost conditions.
  • Because of the extreme cold, there is a layer of permanently frozen ground beneath the surface known as permafrost.
  • The ground's constant sub-zero temperature keeps the soil frozen. Summers may induce only a temporary thawing of the surface layer.
  • It is found across the Arctic regions of the northern hemisphere, north of the subarctic boreal forests.
  • The soils of the tundra may remain permanently frozen, a condition known as permafrost.
  • Roots are unable to penetrate deep into the soil, which inhibits the breakdown of organic materials. The arctic tundra receives very little annual precipitation.
