Look at the picture (the shaded part is the night hemisphere) and answer the following questions: (14 points) (1) The solar terms shown in the picture are & ...

(1) About 22nd in summer and solstice in June? (2) Dark line, 12, 14,18,24 or 0.

③0 degrees, noon sun height (angle), 43 degrees? (4)A and D, B and C

(5) Decreasing from the Tropic of Cancer to the north and south? (6) Arctic Circle and its north, Antarctic Circle and its south

This question examines the comprehensive judgment of the terminator line diagram. (1) shows that the direct point of the sun is located on the tropic of cancer, the ending line is tangent to the polar circle, and there is an extreme day in the Arctic Circle, so it is judged as the summer solstice in the northern hemisphere, and the date is around June 22nd. (2) When the figure enters the night hemisphere from the sun hemisphere along the rotation direction through PDQ and is judged as a dark line, when the D time of the intersection of the dark line and the equator is 18, the time of other points can be calculated. (3) Point D is located on the terminator line, so the sun height is 0, and point A is 12, so its sun height is called noon sun height. The noon sun height at point E can be calculated according to the formula, and the noon sun height = 90-latitude difference. (4) The same latitude means that the height of the sun is the same at noon. (5) The distribution law of midday sun height: decreasing from the direct point (Tropic of Cancer) to the north and south sides. (6) The direct point of the sun is located on the Tropic of Cancer, so there are polar days in and around the Arctic Circle, and polar nights in and south of the Antarctic Circle.
