Test analysis:

(1) According to the longitude information in Figure B, it can be determined that the rotation direction of Figure B is clockwise, so this hemisphere is the southern hemisphere, so Figure A is a schematic diagram of the northern hemisphere.

(2) Because Figure A is the northern hemisphere, the rotation direction is counterclockwise, so along the rotation direction, after the termination line where D is located, the day and night situation is from night to day, so this termination line is the morning line, so point C is the intersection of the equator and the dark line, and the meridian where this point is located is 6 o'clock; From the numerical change of longitude in Figure B, it can be inferred that point A is 135 W, and the longitude of point A is12 in combination with the illumination map; Combined with the above judgment, it is concluded that point C is northwest of point A.

(3) Because Figure B is the southern hemisphere and Figure A is the northern hemisphere, it can be seen that all the Arctic circles are polar nights and all the Antarctic circles are polar days. When the sun is directly on the tropic of Capricorn and 135 W is 12, the position of the direct point is (135 W, 23 26' s); The local time at point C is 6 o'clock, and point B is 3 hours later than point C, so the local time is 3 o'clock; The time and date of point A is 65438+ 12 on February 22, and the longitude is 135 W, so the time and date of Beijing is February 23 15, and the east longitude is 45 to 180, which is 23 days, so it is almost the same day as Beijing.

(4) It can be clearly seen from Figure A that 65,438+0/4 of the latitude circle where Point D is located belongs to the daytime, so the daytime is 6 hours; After the solstice in winter, the days in Hangzhou are short, the nights are long and the days are getting longer and longer.

(5) On the journey from C to D, the interval between two consecutive noons is shorter than that of a solar day because it is consistent with the rotation direction of the Earth.

(6)A is located in the Antarctic circle, and the annual variation of its midday sun height is as follows: at noon on June 22, the sun height is 0, which gradually rises from June 22 to September 23, reaches the maximum at 65438+February 22, and then decreases until it reaches the minimum at 0: 00 on June 22 of the following year.
