At the founding, America adopted the Western concepts of civil marriage and family, in which the mother played the primary role (shared with the father) in nurturing children, with the formation of character and moral values as essential objectives.
Tundra climate, major climate type of the KÃ¶ppen classification characterized by sub-freezing mean annual temperatures, large annual temperature ranges (but not as large as in the adjacent continental subarctic climate), and moderately low precipitation.
The tundra is the coldest biome on Earth, with average annual temperatures ranging from -40Â°F in the winter to 65Â°F in the summer. The winter is much longer than the summer in the tundra, and as a result, the temperature is below freezing (32Â°F) for the majority of the year.
