Read the "two-point map" and "sunshine map" given by answering the questions: (1) When the earth is located in A, the solar terms are ...

(1) vernal equinox; (2)B； ? (3)(22 N， 180)； 8;

(4) The days are long and the nights are short; 88 57′; Decreasing from 22 N to the north and south sides;

(5) Global Environment Facility

Test and analysis: (1) From the position of perihelion and apohelion in the orbit map, B is the summer solstice near apohelion; D is located on the winter solstice near perihelion, so A is vernal equinox. (2) The terminator line chart on the right shows that the rotation direction is counterclockwise, and it is judged as a top view of the northern hemisphere, so it shows that it is extremely daylight within 68 north latitude, so it is judged that the direct point of the sun is located at 22 N, so it is judged as June 22nd 1 week. (3) According to the above analysis, the latitude of the direct point of the sun is 22 N, and the longitude of the direct point of the sun is 12, which means that the bisector of the solar hemisphere is180 meridian. When longitude 180 is 12, Beijing local time 120 E is 4 hours later than longitude 180 local time. (4) The direct point of the sun on that day is located in the northern hemisphere, so the days in Foshan are long and the nights are short; The noon sun height = 90- the latitude difference can be calculated. The global noon sun height decreases from the direct point to the north and south sides. (5) The law of the linear velocity of the earth's rotation: decreasing from the equator to the north and south sides.

Comments: The key to solve this problem is to master the basic contents such as the judgment of the bisector of the track map, the interpretation of the stop line map, the calculation of local time, the latitude distribution law of the noon sun height, and pay attention to the analysis of the basic laws.
