Analysis ①

Students from a geography interest group in a school in China draw the changes and directions of the noon sun height in four places in the world during the year, and answer questions.

Analysis ①: The solar altitude angle is between 60 and 90 (or so) in a year, and the solar altitude angle of the same degree appears twice, so it can be seen that it is located at the equator.

Analysis ②: The annual height angle of the sun is between 45 and 90 (or so). At noon, the direction of the sun is in the north except the direct light, so it can be seen that it is located in the tropic of Capricorn.

Analysis ③: The height angle of the sun is between 45 and 90 (about) in a year. At noon, the direction of the sun is in the south except for direct sunlight, which shows that this place is located in the Tropic of Cancer.

Analysis ④: The annual solar altitude angle in this area is between 0 and 45 (about), and there is extreme sunlight (the noon solar altitude angle is 0). At noon, the sun direction is in the south except direct sunlight, which shows that this area is located in the Arctic Circle.

Answer 5: Only ③ is located on the Tropic of Cancer, which is in line with China's geographical position, that is, the answer is C.

Answer 6:② When the height angle of the sun reaches the maximum at noon, the sun shines directly on the tropic of Capricorn.

Analysis A shows that the earth is at perihelion and its revolution speed is fast.

Analysis B shows that the noon sun is in the south of ① equator, ③ Tropic of Cancer and ④ Arctic Circle.

Analysis C: At this time, it is winter solstice in the northern hemisphere, the school is located in ③ (Tropic of Cancer), and the weather is cold.

Analysis d, at this time, the sun directly hits the tropic of Capricorn, that is, it reaches the southernmost tip, and then it will move north.

So the answer is d.
