(10) The following figure is a schematic diagram of the earth's illumination. Look at the picture and answer the following questions. (1) This graph represents a _ _ _ _ _ hemisphere. (2) The date shown in this drawing is _ _ _

(1) Northern Hemisphere

(2) June 22? Summer Solstice?

(3)C？ d？ 12

⑷DABC

(5)6:00 2:00

(6) decreasing from the tropic of cancer to the north and south.

Test analysis:

(1) According to the counterclockwise interpretation of the earth's rotation direction, this figure represents the northern hemisphere.

(2) Extreme daylight occurs in the Arctic Circle and its north, so the solar term in the northern hemisphere is the summer solstice, that is, around June 22nd.

(3) According to the length of the solar arc, the longest day at point C is 24 hours, and the shortest day at point D is 12 hours, with a difference of 12 hours.

(4) The linear velocity of the earth's rotation decreases from the equator to the poles, so the order from big to small is: DABC.

(5) The intersection of the morning line and the equator is on the same meridian as point B, so point B 180 is 6: 00, and the calculated Beijing time is 2:00.

(6) The direct point of the sun is located on the Tropic of Cancer, so the distribution law of the height of the sun at noon is decreasing from the Tropic of Cancer to the north and south sides.

Comments: This question is a basic question about the movement of the earth. Look at the map carefully, first interpret the north and south poles, and then answer the questions according to the meaning of the questions.
