题目内容
【题目】读太阳光照图(阴影部分代表夜半球)和太阳直射点的回归运动示意图,据图回答下列问题。
(1)ME为晨昏线中的_____线。
(2)当太阳直射点由图乙中③处移向④处时,地球公转的速度变化情况为________。

(4)A点的昼长是_____小时,日落时间是_____点。
【答案】(1)昏
(2)速度越来越快
(3)C F
(4)18 21
【解析】试题分析:
(1)根据晨昏线的判断,顺着地球自转的方向ME处是由昼半球进入夜半球,故为昏线。
(2)考查地球公转速度,靠近近日点速度越来越快,靠近远日点速度越来越慢,图中③处移向④处时地球公转的位置是越来越靠近近日点,故公转速度越来越快。
(3)图中早晨为6点,为晨线与赤道的交点所在的经线为6点,图1中有CF两点。
(4)通E为昏线与赤道交点为18点,与A相差450过计算A点日落时间为21点,计算公式昼长时间=2*(日落时间-12)=2*(12-日出时间),故昼长为18小时。
