Look at the picture and answer the following questions: Question 1: This day is _ _ _ _ _ _ _ _ _ Question 2: C, D,

Question 1: Summer solstice. In the southern hemisphere, the days are short and the nights are long, and extreme nights will appear in the Antarctic circle and its south.

Question 2: When C is 2, D is 6 and E is10; C day length 12 hour, d day length 12 hour, e day length 4 hours.

Question 1: As can be seen from the picture, there is an extreme day phenomenon in the northern Arctic Circle, so the solar term is the summer solstice. At this time, the southern hemisphere is not directly illuminated by the sun, so the days are short and the nights are long, and the polar night extends to the Antarctic circle.

Question 2: First make sure that AB is the morning line and D is on the morning line and the equator, then the time is 6 o'clock. According to the time in D, the time in C and E can be inferred. C and D are both on the equator, so the day length of both places is 12 hour. To find the solution of the day length of e, we can do latitude at point e, find out the time length represented by the arc in the picture at this latitude, and then multiply it by twice the time to get the answer.
