What geographic latitude is known as "north polar"?

The correct answer identifies the geographic latitude known as "north polar," which is defined as being north of 78 degrees North. This classification is significant because it marks the boundary beyond which the climatic conditions and daylight patterns are markedly different from those experienced in lower latitudes. Areas that fall within this range experience extreme cold temperatures, prolonged periods of darkness in winter, and continuous daylight in summer, phenomena characteristic of the polar regions.

In contrast, latitudes lower than 78 degrees North do not experience the same level of polar characteristics. For example, regions north of 60 degrees North are part of the subarctic, where certain seasonal weather effects and daylight variations are present, but they are not as extreme as those at polar latitudes. Similarly, the distinctions become even more pronounced with decreasing latitude, where we find more temperate conditions and a wider range of climatic patterns. Hence, identifying the correct boundary for the "north polar" region is vital for understanding global geography and climate.
