【题目】读经纬网图回答下列各题

1下列关于各点经纬度正确的是( )

A. A点(75°N,165°E) B. B点(60°N,165°W)

C. C点(60°S,150°W) D. D点(45°N,165°W)

2下列说法正确的是( )

A. B点位于东半球、北半球 B. B时间比C早

C. D、E两点正午时刻相同 D. A在B的北方

【答案】

1 D

2 B

【解析】

由经线和纬线相互交织所构成的网络叫做经纬网,利用经纬网可以确定地球表面任何一个地点的位置。在经纬网上,经线的度数叫做经度,若相邻两条经线的经度向东增大,就是东经,用符号E表示,若相邻两条经线的经度向西增大,就是西经,用符号W表示;纬线的度数叫纬度,若相邻两条纬线的纬度向北增大,就是北纬,用符号N表示,若相邻两条纬线的纬度向南增大,就是南纬,用符号S表示。D. E两点位于不同的经线上,因此正午时刻不相同

1据图可知:A点的坐标是(75°N,165°W);B点的坐标是(60°N,165°E);C点的坐标是(60°N,150°E);D点的坐标是(45°N,165°W),故本题选D。

2据图可知:B点位于北半球、西半球;B点位于C点的东侧因此时间比C早;根据“经线指示南北方向,纬线指示东西方向”来确定AB的东北方向,故本题选B。

本题主要考查经纬网的判读以及半球的划分时间、方向的判断等知识要求学生掌握必要的地理知识。
