sparse precipitation and extreme cold temperature.

The correct answer is A. Tundra is known for its sparse precipitation and extreme cold temperatures.

Explanation:

A tundra is an area without high plant growth adjacent to a polar area. The vegetation consists of grasses, mosses, lichens and dwarf shrubs.

The general climate on a tundra is very unfavorable for the growth of higher plants. The soil has been frozen or covered with snow for at least six months. The growing season is very short and the average temperature of the hottest month is below 10°C. During the summer, only the top layer defrosts from the bottom, over a depth of 30 to 60 cm above the permafrost. Although the amount of precipitation is relatively small, most soils on a tundra are swampy. This is because the water cannot sink into the frozen substrate and because the evaporation is also very low.
