Look at the picture and complete the related questions. (1) The solar terms represented in this diagram are _ _ _ _ (Northern Hemisphere), and the coordinates of the direct point of the sun are _ _ _ _ _ _ _ (2) in the diagram. (1) According to the analysis in the figure, the extreme sunlight phenomenon in the Arctic Circle and its northern area indicates that it is the summer solstice. On the summer solstice, the direct sunlight is at 23 26 ′ n, and the longitude of the direct sunlight spot is the longitude of meridian 12 when looking for the location. According to the fact that the meridian at the intersection of the morning line and the equator is at 6 o'clock, it can be judged that the meridian at point A is at 6 o'clock, from which 6544 can be calculated.

(2) According to the direction of the earth's rotation, it can be judged that both A and B are located on the morning line, while the second place is located on the morning line at sunrise, and the local time of the second place is 4 o'clock at this time.

(3) According to the analysis of the first sub-topic, when the longitude of 180 is 12 and Beijing time is 120 E, Beijing time can be calculated as 8 o'clock according to the longitude difference. Nanjing Zhongshan Station is located in the Antarctic Circle, and the Antarctic Circle and its south area are extremely dark from summer to morning, so the night length of Zhongshan Station is 24 hours.

(4) During the summer solstice, the noon sun height of the Tropic of Cancer and its north reaches the maximum in a year. Therefore, it is chosen as ABD.

(5) From summer solstice to autumnal equinox, the days in the northern hemisphere become shorter and the nights become longer, so the days in Harbin become shorter and the nights become longer, and the height of the sun gradually decreases at noon.

So the answer is:

(1) summer solstice 23 26' n 180.

(2) 4 am

(3)8? 24

ABD

(5) The days are shorter and the nights are longer.
