24 solar terms geography brief answer junior high school

There is a mistake. The answer should be B. The days are long and the nights are short.

Because 65438+1October 12 (the tenth day of the ninth lunar month) is the "white dew" among the 24 solar terms, the next solar term is the "autumnal equinox". After the Autumn Equinox, the days are short and the nights are long in the northern hemisphere, while China is located in the northern hemisphere.

Please see:

Autumnal equinox: the barrel refers to itself. The solar line is 180. The autumnal equinox and the vernal equinox are the same. The sun shines almost directly on the equator, and day and night are almost equal. From this day on, the position of direct sunlight continued to move from the equator to the southern hemisphere, and the days became shorter and the nights became longer in the northern hemisphere. According to China's autumnal equinox theory, this day is exactly half of the ninety days in autumn, so it is called autumnal equinox. But in astronomy, it is stipulated that autumn in the northern hemisphere begins with the autumnal equinox.
