Answer:
PERMAFROST LAYER
Explanation:
Permafrost layer is usually defined as the thick layer of soil that is mixed with the broken rock fragments and other sediments, and are covered by ice throughout the year. These are mostly found in the higher latitudinal region, where the thickness of these layers ranges from a few meters to tens and hundreds of meters. The melting of these layers in these regions leads to an increase in the sea level.
For example, the permafrost layers of tundra and subarctic zones in Russia and its nearby areas, which have a thickness of about three meters.

Answer:
A: Frozen taiga
Explanation:
Russia is the largest country in the world, and its land has several different characteristics. One of them though dominates by far, and that is the taiga, which is occupying more area than all of the other biomes in the country combined.
The taiga is stretching across all of the country from west to east, while the rest of the biomes are north and south of it. The land is covered with dense coniferous forests, representing the largest continuous forest in the whole world.
The taiga is not the most pleasant place for living though. The majority of the year is winter, and the temperatures are extremely cold, and in some parts of it they are as low as in Antarctica. There is lot of snowfall, usually several meters deep. The short summers are mild and very humid. Everything defrosts so big portion of the taiga is becoming marshy.
