Look at the picture (shaded part indicates night) and answer the following questions. (1) This picture shows _ _ _ _ _ _ days (solar terms). (2) the rotation lines of points a, d and e.
(2) The linear rotation speed of the earth gradually decreases from the equator to the north and south sides, and the order of the linear rotation speed of points A, D and E from small to large is EDA;; Under the action of geostrophic deflection force, the horizontally moving object in the southern hemisphere deflects to the left, and a shell is fired from point D to point B, which will land on the east side of the meridian where points D and B are located.
(3) From winter to sunrise in the northern hemisphere, the sun shines directly on the Tropic of Capricorn; According to the direction of the earth's rotation, the central longitude is 90 E at night and 90° w during the day.
(4) Point E is located in the Antarctic Circle, and the Antarctic Circle and its south area are extremely bright, with a day length of 24 hours; According to the night arc (2 squares, 3 hours each) at the latitude where point B is located, it can be judged that the night length is 6 hours, and the sunrise time =0+ night length /2=3 points; Point C is located at the equator, and the sun shines directly on the Tropic of Capricorn. According to the formula for calculating the noon sun height, H = 90°- the latitude difference between them = 66 34'; Point A is the intersection of the morning line and the equator, and the height of the sun on the terminator line is equal to 0.
(5) Point C is located at the equator. At noon, the direct point of the sun is located in its north, and the direction of the sun shadow is opposite.
(6) During the winter solstice, the height of the sun decreases from the tropic of Capricorn to the north and south sides at noon.
(7) In three months, on March 2 1 day, the sun will shine directly at the equator, and the world will be divided equally between day and night.
So the answer is:
(1) winter solstice?
(2) East Ida
(3)(23 26 inches, 90 watts)
4 24 hours 3? 66 34′0
(5) due south?
(6) decreasing from the tropic of Capricorn to the north and south sides?
(7) The length of day and night is equal
