【題目】大同市白晝最短時,同學們即將過的節(jié)日是 ( )

A.元宵節(jié)B.圣誕節(jié)C.中秋節(jié)D.國慶節(jié)

【答案】B

【解析】

地球繞太陽不停的旋轉(zhuǎn),叫地球的公轉(zhuǎn),公轉(zhuǎn)的方向是自西向東,周期是一年。地球圍繞太陽公轉(zhuǎn)時,地軸與公轉(zhuǎn)軌道的平面成66.5°的固定傾角,這就使得一年內(nèi)太陽光線的直射點有規(guī)律地在南北回歸線之間移動。當太陽光線直射赤道時是北半球的春分日或秋分日,此時全球晝夜等長;當太陽光線直射北回歸線時是北半球的夏至日,北半球晝長夜短,北極地區(qū)出現(xiàn)極晝現(xiàn)象;當太陽光線直射南回歸線時是北半球的冬至日,北半球晝短夜長,北極地區(qū)出現(xiàn)極夜現(xiàn)象。

當太陽光線直射南回歸線時是北半球的冬至日,日期為12月22日前后,北半球晝最短夜最長;此時我們即將過圣誕節(jié)(12月25日);故選:B。
