Solar terms of earth rotation and direct solar point

Xi, the capital of Shaanxi Province in People's Republic of China (PRC), is located in the north of the Tropic of Cancer and belongs to the northern hemisphere.

(3) According to the schematic diagram of the revolution of our ball, when our ball runs to ③, the latitude of direct sunlight is the equator, which is the autumnal equinox in the northern hemisphere, and the global day and night are equally divided.

(2) According to the schematic diagram of our ball revolution, when our ball revolves to 1 o'clock, the latitude of direct sunlight is the equator, which is vernal equinox in the northern hemisphere. From this day on, the direct sunlight will continue to move northward, and the height of the sun in the northern hemisphere will continue to increase at noon.

(3) According to the schematic diagram of our ball revolution, when our ball revolves to ②, the sun shines directly on the Tropic of Cancer, which is the summer solstice in the northern hemisphere. At this time, the tropic of cancer and its north area have the largest height angle of the sun and the shortest shadow at noon.

(i) My ball rotates from west to east.

(5) According to the schematic diagram of our ball revolution, when our ball revolves to ④ o'clock, the latitude of direct sunlight is tropic of Capricorn, which is the winter solstice in the northern hemisphere, and the date is around1February 22nd; Our national day is March 3, about the 23rd day of the autumnal equinox and the 22nd day of the winter solstice. So we can see that our ball is running between ③ and ④.

So the answer is: (3) vernal equinox; Equator; Divide day and night equally; (2) increase; (3) the shortest; Tropic of Cancer; Summer solstice; ㈠； (5)C。
