【题目】某点以西为东半球,以东为西半球,以南为南半球,以北为北半球,符合以上条件的点是
A.180°、0°B.160°E、0°
C.20°W、20°ND.0°、0°
【答案】B
【解析】
南北纬度的划分都是以赤道(0°纬线)为界,赤道以北的属北纬,用符号“N”表示,所有的北纬都在北半球,赤道以南的属南纬,用符号“S”表示,所有的南纬都在南半球;东西半球的划分是以20°W和160°E组成的经线圈为界,东半球的经度范围为20°W→0°→160°E,西半球的经度范围为160°E←180°←20°W。
东西半球分界线是20°W和160°E组成的经线圈,0°W以东、160°E以西为东半球,20°W以西、160°E以东为西半球。赤道是南北半球的分界线,以南是南半球,以北是北半球。据此判断,该点以西为东半球,以东为西半球,则该点位于160°E经线上,以南为南半球,以北为北半球,则该点位于赤道即0°纬线上。故选:B
