Question 1: The chart determines the earth's axis according to the light of Polaris, so the chart indicates that the sun shines directly near the tropic of Capricorn, indicating the winter solstice in the northern hemisphere.

Question 2: When is it in the picture? In the process of gradually reducing the angle from the current situation to 0, that is, from winter solstice to vernal equinox, the polar night range in the Arctic Circle will be reduced from the Arctic Circle to the North Pole;

Question 3: If the day length of A is 10 hour, then the sunrise time is 7: 00 a.m., which is the time for it to pass the morning line. But the intersection of the morning line and the equator is 6: 00, and the longitude is 0, so the meridian at 7: 00 should be 65,438+05 E.
