Final answer:
Russia's major climate type is subarctic, and the major biome is the boreal forests, characterized by cold, dry winters, and short, cool, wet summers.
Step-by-step explanation:
The statement that the major climate type in the Russian region is subarctic, and the major biome is boreal forests is true. The boreal forest, also known as taiga or coniferous forest, is found south of the Arctic Circle and across most of Russia. This biome has cold, dry winters and short, cool, wet summers. The annual precipitation is from 40 cm to 100 cm (15.7-39 in) and usually takes the form of snow. Little evaporation occurs because of the cold temperatures, which falls in line with subarctic climate conditions.
