【题目】东西半球的分界线是( )

A.0、180B.20W、160E

C.20E、160WD.90W、90E

【答案】B

【解析】

根据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,进行分析解答。

东西半球分界线是20°W160°E组成的经线圈,20°W以东、160°E以西为东半球,20°W以西、160°E以东为西半球。故选项B符合题意。故选:B
