Read the dichotomy chart (left) and the sunshine chart of a certain day (right) and complete the following questions. (The shaded part in the figure indicates the night hemisphere, and the dotted line indicates the polar circle.

(1) winter solstice; Autumnal equinox (4 points)

(2) small; ? 24? (4 points)

(3)A & lt； D & ltB& lt； c； A and B(4 points)

(4)B& gt； C & gta； A>C & gtB(4 points)

Test analysis:

(1) As can be seen from the figure: ① The sun shines directly on the Tropic of Capricorn, which should be the solstice in winter; ④ The process from summer to the east should be the autumnal equinox.

(2) At this time, it is the polar day in the Antarctic circle, indicating that the sun is directly on the Tropic of Capricorn, and the noon sun height in Beijing should reach the minimum value in a year; The last day and night at point A in the Arctic Circle was 24 hours.

(3) Linear speed is inversely proportional to latitude, as can be seen from the figure: C

(4) The height of the sun at noon is related to the latitude of the direct point of the sun. The closer the distance, the higher the height of the sun at noon, which shows that B >; C & gta； At this time, the sun shines directly in the southern hemisphere, and the farther south, the shorter the night is, and A>C> B can be obtained.
