(2) According to the rotation direction of the earth, it can be judged that both A and B are on the dark line. Draw the latitude circle of B. According to the length of the solar arc, it can be calculated that the day length of B is 18 hours and the sunrise time is = 12- day length /2, so the sunrise time of B is 3 o'clock.
(3) According to the latitude of Kunlun Station, it can be seen that Kunlun Station is located in the Antarctic Circle, and it is winter solstice, and the Antarctic Circle and its south area are extremely daytime, so the night of Kunlun Station is 0: 00. According to the rotation direction of the earth, B is in the east of A and B is in the south of A, so B is in the southeast of A. 。
The summer solstice will be in six months. From summer to the sun, the height of the tropic of cancer and its north noon sun reaches the maximum in a year, and reaches the minimum in all parts of the southern hemisphere, so AD is chosen.
