Read the "Earth Illumination Map" and answer the following questions. (1) is about _ _ _ _ _ _ _ (solar terms) in the northern hemisphere. If the longitude of point C is 180, the sun is in direct sunlight. (1) According to the map analysis, the phenomenon of extreme night appeared in the Arctic Circle and its northern region at this time, indicating the winter solstice in the northern hemisphere. The latitude of the direct sunlight is 23 26' s, and the longitude of the direct sunlight point is 12 when looking for a place. According to the longitude of the intersection of the dark line and the equator at 18: 00, it can be judged that point C is 20, and

(2) At this time, point A is located on the termination line, so the sun height of point A is 0. According to the calculation formula of noon sun height, it is substituted as 90-(23 26 ′ s+23 26 ′ n) = 43 08 ′.

(3) According to the length of the night arc at the latitude of point B, it can be seen that there are 2.5 squares in the night hemisphere, and one square is 2 hours, so the night length of point B we see is 5 hours plus the invisible part, so the night length of point B is 10 hour and the day length is 14 hour. Sunrise time = 12.

(4)A is located between the Tropic of Cancer and the Arctic Circle and belongs to the north temperate zone.

So the answer is:

(1) Winter solstice, 23 degrees 26 minutes south latitude, 60 degrees east longitude.

(2)0 43 08′

(3) 10 5:00 20:00

(4) the temperature in the north
