Look at the picture (shaded part indicates night) and answer the following questions. (1) This picture is _ _ _ _ _ _ (solar terms), and the date is _ _ _ _ _ _ _ _ _.

(1) From 45 E and 90, it can be judged that the direction of the earth's rotation is clockwise. Looking down from the South Pole, the polar sun appeared in the Antarctic circle and its northern region, with the time of 65438+February 22.

(2) The Antarctic Circle and its northern area are extremely bright, and the sun shines directly on the Tropic of Capricorn; 90 E is located in the center of night, 90 W in the center of day, and the direct geographical coordinates are (23 26 ′ s, 90 W).

(3) The linear speed of rotation decreases from the equator to the poles, a > d > e. Objects moving horizontally in the southern hemisphere are deflected to the left by the geostrophic deflection force, and the shells fired at point D will land on the east side.

(4) The latitude of point B (grid method) is 6 hours at night, 3 o'clock at sunrise and 2 1 point at sunset.

(5) Point A is located at the equator, equally divided day and night; Point B is located in the Antarctic circle, and the length of polar day and night is 0.

(6) The difference between A and C is 180. Take the polar route, first due south and then due north.

(7) There are two solar lines, one at 0 o'clock and the other at longitude 180. 90 E is located in the center of the night, at 0: 00 local time, at a point 180. According to the direction of the earth's rotation, a is located in 180 to 90 E, accounting for 3/ of the global area.

So the answer is:

(1) winter solstice; 65438+February 22nd.

(2)(23 26, 90 W). ?

(3)A > D > E； East side.

(4)3; 2 1.？

(5) 12; 0.

(6) answer.

(7)D。
