The tundra is the olive-green areas. They cover the north of Canada and the top of Russia and Siberia. Most of Alaska is also part of the tundra, and the entire continent of Antartica is part of the tundra. (Antartica is also the largest desert in the world.) The tundra covers 20% of the Erath.
SeasonsThere are no specific seasons, except the permanent winter. There is a “growing season” where plants and crops grow for 60 days. The rain falls in the “summer.”

TemperatureThe temperature is very low, very often. It is usually in the range of -40*C to 18*C, or -40*F to 64.4*F. That warmness is a rarity.

Unique Issues
Any and all thawing only exists in the first few inches of topsoil, and the thaw only lasts for around sixty days, or two months. The sun rarely comes up, but when it does, it lasts all day and night. This can cause major erosion issues.

PrecipitationThe rain rates are extremely low in tundras. The amount of rain is less than the rates in most deserts. There are fogs and water in bogs, but that's about it. The amount of rain is from 15m to 25m, and this also counts melted snow. (6 to 10 inches)

Types Of Soil
The soil in the tundra is extremely acidic and has little to no nutrients. That is why very small amounts of plant life live there. During the so-called “summer,” the first few inches thaw for a growing season, but everything under that is permafrost.
