Look at the picture and answer the following questions. (1) The solar term in the northern hemisphere that day was _ _ _ _ _. (2) At this time, the latitude of the sun's direct point is _ _ _ _ _ _ _ _ _ _, and the longitude is _ _ _ _ _ _. (1) clockwise from the south pole, the Antarctic circle and its south area are extremely bright, which is the winter solstice in the northern hemisphere.

(2) On the solstice in winter, the sun shines directly on the tropic of Capricorn. According to the change of longitude in the rotation direction in the figure, the meridian of the sun is 90 e.

(3) According to the rotation direction, line AB in the figure is the morning line from night to day.

(4) Point C is the intersection of the dark line and the equator, and the local time is 18. According to "the east is early and the west is late, and the east is added and the west is reduced", the point D is 3 hours earlier than the point C, and the local time is 21; According to the latitude of point D, the solar arc is 6 grids, each grid is 3 hours, and the day length of point D is18; Sunrise time = 12 day length /2=3 o'clock.

(5) From winter to the sun, polar nights appear in the Arctic Circle and its north, and the sun shines directly on the Tropic of Capricorn. The noon sun height in the northern hemisphere is the minimum in a year.

(6) The rotational linear velocity gradually decreases from the equator to the north and south sides, and the order of the central linear velocities of A, B and D in the figure is ADB；; In the winter solstice, the days are long and the nights are short in the southern hemisphere. The higher the latitude, the longer the day and the shorter the night. The order of days from long to short is BDA. ..

(7) The formula for calculating the noon sun height is h = 90- the latitude difference between them = 90-(66 34'-23 26') = 46 52'.

So the answer is:

(1) winter solstice

②23 26? 90 degrees east longitude

(3) in the morning.

(4)2 1? 18? three?o'clock

(5) North latitude 66 34' to 90 0 to 90.

(6) ADB? BDA

(7)46 52′
