Here's why:

* Location: The Arctic Tundra is found in the northernmost regions of the world, encircling the Arctic Ocean.

* Climate: It's characterized by extremely cold temperatures (average below freezing for most of the year) and limited precipitation, primarily in the form of snow.

* Permafrost: One of the key features is permafrost, a layer of permanently frozen soil. This makes it difficult for deep-rooted plants to grow.

* Short Growing Season: The short, cold summers allow only a brief period for plant growth.

* Unique Adaptations: The plants and animals that survive in the Arctic Tundra have developed unique adaptations to cope with the harsh conditions.
