Look at the picture and answer the following questions. (1) This is the illumination map of _ _ _ _ _ days (solar terms) in the northern hemisphere, and the judgment basis is _ _ _ _ _ _. (2) The direct point of the sun at this time. (1) In the picture, extreme days appear in the Arctic Circle and its northern region, which is the summer solstice in the northern hemisphere.

(2) Extreme days appear in the Arctic Circle and its northern region, which is the summer solstice in the northern hemisphere, and the sun shines directly on the Tropic of Cancer.

(3) According to the direction of the earth's rotation, the morning line is from night to day.

(4) The night arc at latitude of point D is 8 grids, each grid is 2 hours, and the night length is 16 hours; Point E is located at the direct point of the sun, and the height of the sun is 90 at noon.

(5) Point B is located at the equator, equally divided day and night; Point B is on the morning line, and the height of the sun on the terminator line is 0.

(6)A is located on the west side of point B, with a difference of 3 grids, each grid is 2 hours, and the time difference between A and B is 6 hours.

(7) The local time on the same longitude line is equal, and the local time of each point in the figure is equal to that of place A..

So the answer is:

(1) The summer solstice is the polar day in the Arctic Circle (the polar night in the Antarctic Circle).

(2)23 26? N (Tropic of Cancer)?

(3) in the morning?

(4) 16 90

(5) 12 0

(6)6

(7)D
