Final answer:
The statement is true; the Arctic tundra biome is found at high latitudes throughout the Arctic regions of the Northern Hemisphere and at high mountain elevations above the tree line.
Step-by-step explanation:
The statement that the biome of the Tundra is found only near the Arctic Circle at high latitudes is true. The Arctic tundra is indeed located throughout the Arctic regions of the Northern Hemisphere, lying north of the subarctic boreal forests, also known as the taiga. This biome extends to the most northern latitudes and can also be found at elevations above the tree line on mountains. The tundra is characterized by extremely cold winters with average temperatures of about -34°C (-29.2°F) and cool summers, averaging between 3°C and 12°C (37°F-52°F). The growing season is notably short, lasting only about 50-60 days, but it benefits from nearly 24 hours of daylight, fostering rapid plant growth.
