问题 综合

读太阳光照图(左图)和“太阳直射点的回归移动示意图”(右图),完成下列要求。(8分)

(1)在左图上画出晨昏线和夜半球。(2分)

(2)左图所示这一天,图中A、B两地先见到日出的是       ;A、B、C三地的白昼长短关系是                               

(3)这一天,正午太阳高度由          (纬度)向南北两侧降低;正午太阳高度达到一年中最大值的范围是                             

(4)右图中北半球昼变短、夜变长的时段是                   (多选)。

A.①—②       B.②—③     C.③—④      D.④—⑤

答案

(1)图略(晨昏线与夜半球各1分,共2分)

(2)B(1分)      C>A=B(1分)

(3)23°26′S(1分)   南回归线及其以南(1分)

(4)BC(2分,答对一个得1分)

题目分析:(1)晨昏线过地心,与阳光相垂直,背对阳光一侧为夜半球。(2)图示AB位于同一纬线上,故越往东日出越早,故B点较A点早看到日出。左图所示,太阳直射点位于南回归线上,故全球昼长的分布规律:越往南昼越长;AB位于同一纬线上,故昼长相等。(3)该日,太阳直射点位于南回归线上,正午太阳高度的分布规律:自直射点向南北两侧递减。此日为北半球冬至日,北半球正午太阳高度达一年中最短;而南回归线以南地区,正午太阳高度达一年中最短。(4)北半球昼变短、夜变长,及太阳直射点向南移。

点评:本题解题的关键是能抓住图示太阳直射点的位置判断二分二至节气,并利用太阳直射点的移动判断昼夜长短、正午太阳高度的变化等内容。对于此类试题,学生在平时的学习中应加强对基本方法的整理和归纳。
