Read the screenshot of the weather forecast of a city in China and complete the following questions. Question 1: among the following solar terms, the closest to that day is a. vernal equinox B.

Question 1:B?

Question 2:C

Question 3: a?

Question 4:C

Test analysis:

Question 1: It is inferred from the sunrise time of 4:20 and the sunset time of 19: 40 that the day length of this place is about 15 hours. The vernal equinox and autumnal equinox should be the same length as day and night, each 12 hour, and options A and C are wrong; The day length from winter to sun is less than 12 hours, and option d is wrong; Summer solstice is shorter than 12, so the corresponding solar term should be summer solstice. Option b is correct.

Question 2: The solar term is summer solstice, and the direct point of the sun is in the northern hemisphere; Knowing the sunrise and sunset time of today and tomorrow, the sunrise time will be delayed, and the sunset time will be met, we can calculate that the day will become longer and shorter, which proves that the direct point of the sun moves south. So after the solar term, the direct point of the sun is in the northern hemisphere and moves south. Option c is correct.

Question 3: Because the day length from summer to morning at 40 north latitude is 14: 5 1 minute, and the day length of the city is 15 hours and 20 minutes, the city is north of 40 north latitude, and the latitude of Harbin is about 45° N；; ; The latitude of Luoyang is about 35° N；; ; The latitude of Guangzhou is about 23 26' north latitude; The latitude of Haikou is about 20 north latitude, so only Harbin meets the requirements. Option a is correct.

Question 4: The circle in the picture represents the latitude circle, the shaded area on the circle represents the night arc, and the unshaded area represents the day arc. When the sun shines directly in the northern hemisphere, the length of Moscow during the day should be longer than that at night. Option c is correct.
