What type of climate is commonly found in Alaska?

C is the correct answer because Alaska is primarily characterized by a subarctic climate, especially in the central and northern parts of the state. The subarctic climate is defined by long, harsh winters and short, mild summers, with significant temperature variations between seasons. This climate leads to specific vegetation patterns, such as boreal forests, and has a significant impact on wildlife and human activities in the region.

In contrast, tropical climates, which are known for warm temperatures and high humidity throughout the year, are not found in Alaska due to its high latitude. An arid climate, characterized by low precipitation and high evaporation rates, does not apply to Alaska's overall conditions, as the state receives a considerable amount of snowfall and rainfall, particularly in coastal areas. While certain parts of Alaska, particularly in the interior, may exhibit features of a continental climate—such as more extreme temperature variations than coastal areas—this is less representative of Alaska as a whole compared to its extensive subarctic regions.
