读图,若阴影表示夜半球,且C点所在的经度为0°,完成:38—40题

小题1:据图判断,此刻太阳直射点的坐标为

A.(0°,0°)

B.(90°E,0°)

C.(90°E,23°26′N)

D.(90°W,23°26′N)小题2:下列关于A点的说法正确的是

A.位于东半球,C点的西北方向

B.日期与C点在同一天

C.昼长为16小时

D.正午太阳高度为0°小题3:此后三个月内,下列说法正确的是

A.地球的公转速度先变慢后变快

B.深圳的正午太阳高度先减小后增大

C.开普敦逐渐进入温和多雨的季节

D.悉尼的昼夜长短相差越来越大

答案

小题1:C

小题2:C

小题3:A

小题1:本题考查太阳光照图的判断。根据北极圈及其以北地区出现极昼现象,判断太阳直射点的纬度为23°26′N。根据C点经度为0°,判断太阳直射点的经度为90°E。所以本题选择C选项。

小题2:A点此刻位于昏线上,地方时为20:00,经度为150°W,所以A点位于西半球,在C点的正西方向;和C点分属两个不同的日期;昼长为18小时;正午太阳高度大于0°。所以本题选择C选项。

小题3:此后三个月内从夏至到秋分,远日点的时间为7月初,地球公转速度先变慢后变快;深圳位于赤道与北回归线之间,深圳的正午太阳高度先增长后减小;悉尼和开普敦位于南半球,开普敦温度逐渐升高,降水不断变少,悉尼昼夜长短的差值原来越小。所以本题选择A选项。
