【題目】某點(diǎn)以西為東半球,以東為西半球,以南為南半球,以北為北半球,符合以上條件的點(diǎn)是

A.180°、0°B.160°E、0°

C.20°W、20°ND.0°、0°

【答案】B

【解析】

南北緯度的劃分都是以赤道(0°緯線)為界,赤道以北的屬北緯,用符號(hào)“N”表示,所有的北緯都在北半球,赤道以南的屬南緯,用符號(hào)“S”表示,所有的南緯都在南半球;東西半球的劃分是以20°W160°E組成的經(jīng)線圈為界,東半球的經(jīng)度范圍為20°W0°→160°E,西半球的經(jīng)度范圍為160°E180°←20°W

東西半球分界線是20°W160°E組成的經(jīng)線圈,0°W以東、160°E以西為東半球,20°W以西、160°E以東為西半球。赤道是南北半球的分界線,以南是南半球,以北是北半球。據(jù)此判斷,該點(diǎn)以西為東半球,以東為西半球,則該點(diǎn)位于160°E經(jīng)線上,以南為南半球,以北為北半球,則該點(diǎn)位于赤道即0°緯線上。故選:B
