(1) Summer solstice; ? June 22nd? (2 points) (2) 0; 12; 16? (3 points)

(3) early line; b； Long days and short nights (or "longest days and shortest nights") (3 points)

(4) a? ( 1)

This topic examines the comprehensive analysis of the light map. (1) According to the terminator line characteristics shown in the diagram: the terminator line is tangent to the polar circle, and an extreme day appears in the Arctic Circle, which is judged as the summer solstice in the northern hemisphere; (2) The polar night appears at point A, so when the day length is 0, point B is located at the equator, and the day length is 12 hours. The sunrise time at point C is 4 o'clock, so the calculated day length is 16 hours. (3) The graph follows the rotation direction and passes through the terminator line, which is about to change from the night hemisphere to the day hemisphere, so it represents the law that the rotation linear speed decreases from the equator to the poles in the morning line. At this time, the direct point of the sun is located in the northern hemisphere, so the days in the northern hemisphere are long and the nights are short. (4) The geostrophic deflection of the equator is zero. The higher the latitude, the greater the geostrophic deflection and the more obvious the deflection.
