This topic examines the revolution of the earth and the judgment of the terminator line. (1) According to the diagram, the terminator line is tangent to the polar circle, and the polar night appears in the Arctic Circle, so it is judged as the winter solstice in the northern hemisphere, and the date is 65438+February 22. (2) According to the position of the sun's direct point on the orbit map, it is judged that the sun's direct point at position B is located on the tropic of cancer, and it is judged as the summer solstice; The direct point of the sun at position D is located on the tropic of Capricorn, and it is judged as the winter solstice, so C stands for the autumnal equinox and A stands for the vernal equinox. (3) The point of direct sunlight on the right is located in the southern hemisphere, so the days in the southern hemisphere are long and the nights in the northern hemisphere are short. (4) The position B in the figure is the summer solstice, and the latitude of the direct point of the sun is 23.5 N, so the height of the sun decreases from the Tropic of Cancer to the north and south sides at noon. (5) The days are long and the nights are short in the southern hemisphere, which means that the direct sunlight point is located in the southern hemisphere. When the days are shorter and the nights are longer in the southern hemisphere, it means that the direct sunlight point moves northward, so it is judged as the winter solstice-vernal equinox.
