Read the schematic diagram of the earth's revolution and complete the following questions. (1) When the earth revolves to place A, the latitude of direct sunlight is _ _ _ _ _, and the solar terms in Luzhou are _ _. Luzhou City is located in the southeast of Sichuan Province, China, where the Yangtze River meets the Tuojiang River. It is an important port in the upper reaches of the Yangtze River and a channel for Hainan to enter Sichuan, belonging to the northern hemisphere.

(1) As can be seen from the schematic diagram of the earth's revolution, when the earth is in position A, the sun is facing the Tropic of Cancer, which is the summer solstice in the northern hemisphere, and the date is around June 22nd. At this time, the length of day and night in the northern hemisphere is the longest day, the shortest night, and the Arctic Circle is extremely day.

(2) It can be seen from the schematic diagram of the earth's revolution that when the earth is in position C, the latitude of direct sunlight is tropic of Capricorn, which is the winter solstice in the northern hemisphere, and the date is about 65438+February 22nd. The length of day and night in the northern hemisphere is as follows: the shortest day and the longest night, and the phenomenon of extreme night appears in the Arctic Circle.

(3) As can be seen from the figure, the earth axis is always inclined relative to the track plane.

(4) When the earth is in position B, the latitude of direct sunlight is the equator, which is the autumn equinox in the northern hemisphere, and the date is around September 23rd. When the earth is in position C, it is the winter solstice in the northern hemisphere, and the date is about 65438+February 22. So we can see that 2011.1.65438.

So the answer is: (1) Tropic of Cancer; Summer solstice; Around June 22; Longest; Shortest; Extreme day; (2) Tropic of Capricorn; Solstice of winter; 65438+around February 22nd; Shortest; Longest; Extreme night; (3) tilt; (4)B； C.
