What is the most distinctive characteristic of tundra soil?
The most distinctive characteristic of the tundra soil is permafrost. Permafrost is a permanently frozen layer of ground. Permafrost can also be found in the coldest regions of the taiga. During the short summers in the tundra, the top section of the soil may thaw out.
What is tundra soil made of?

What type of vegetation is found in the tundra region?
Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus.
Where are tundra soils found?
Tundra soils form in cold environments. Tundra soils form in cold environments with short growing seasons and harsh winters. These soils may be at high elevation (mountains) or high latitude (arctic or Antarctic).
What is the frozen soil of the tundra?
Answer and Explanation: The frozen ground in a tundra ecosystem is known as permafrost. Even during the summer months, the deeper layers of this soil remain frozen.
Is a tundra wet or dry?
Still, the tundra is usually a wet place because the low temperatures cause evaporation of water to be slow. Much of the arctic has rain and fog in the summers, and water gathers in bogs and ponds. Vegetation in the tundra has adapted to the cold and the short growing season.
