Which of the following best explains why the Inuit principally relied on hunting for survival? Group of answer choices A.Tundra
Allushta [10]

Answer:

Option (A)

Explanation:

The Inuits refers to those people that live in the Arctic region, such as Greenland, the northern region of Canada, as well as Alaska. The region in which they live can be considered as tundra, which is characterized by the presence of low temperature, dry wind, shorter duration of seasons, and lack of vegetation. This type of region is found in the polar and near-polar areas and in the high altitude areas.

The climate of tundra is very cold, and there occurs the layer of permafrost in the soil, and it does not provide the essential conditions for the growth of plants. The growth of crops is hindered by the shorter season, lack of sunlight and low precipitation.

This is why the Inuits are dependent on hunting for heir survival

Thus, the correct answer is option (A).
