(3) Answer

(4) North? Tropic of Cancer and Its Northern and Southern Hemisphere

Test analysis:

(1) This question examines the position of the earth in the orbit from the bisector to the sun. A is the summer solstice, B is the autumnal equinox, C is the winter solstice, and D is the vernal equinox.

(2) This question examines the change of the height of the sun at noon and the length of day and night. When the earth is at point C, the corresponding solar term is the winter solstice, and the direct point of the sun is in Capricorn. The sun height in Capricorn and its south reaches the maximum in a year at noon. Capricorn's sun height is 90, so the northern hemisphere has short days and long nights, so Beijing has short days and long nights.

(3) This topic examines the monsoon climate in eastern China, which is hot and rainy in summer. When the earth rotates to position A, it is summer in the northern hemisphere.

④D is the vernal equinox, and A is the summer solstice. From D to A, the direct point of the sun is located in the northern hemisphere and moves northward. From summer to the sun, the sun shines directly on the Tropic of Cancer, and the noon sun height in the Tropic of Cancer and its north reaches the maximum in a year, while the sun height in the southern hemisphere reaches the minimum in a year.

Comments: According to the position of the direct point of the sun, the position of the earth in the orbit of revolution, and the length of day and night in the northern and southern hemispheres, we can judge the solar terms of the earth. From summer to morning in the northern hemisphere (around June 22), the sun shines directly on the Tropic of Cancer, the days in the northern hemisphere are long and the nights are short, and the Arctic Circle and its north are extremely day. During the winter solstice (about 65438+February 22nd), the sun shines directly on the Tropic of Capricorn, and the days in the northern hemisphere are short and the nights are long, and the Arctic Circle and its northern region are extremely night. At the equinox, the sun shines directly at the equator, and the whole world is as long as day and night.
