【題目】關(guān)于經(jīng)線和緯線的正確敘述是:( )
A.所有經(jīng)線的長(zhǎng)度皆相等;B.所有經(jīng)線都與本初子午線平行;
C.所有的經(jīng)線圈和緯線圈都能平分地球;D.45°緯度的長(zhǎng)度是0°緯線的一半。
【答案】A
【解析】
根據(jù)連接南北兩極的線,叫經(jīng)線。和經(jīng)線相垂直的線,叫緯線。緯線是一條條長(zhǎng)度不等的圓圈.最長(zhǎng)的緯線,就是赤道;因?yàn)榻?jīng)線指示南北方向,所以,經(jīng)線又叫子午線;國(guó)際上規(guī)定,把通過(guò)英國(guó)格林尼治天文臺(tái)原址的那條經(jīng)線,叫做0°經(jīng)線,也叫本初子午線。在地球上經(jīng)線指示南北方向,緯線指示東西方向,進(jìn)行分析解答。
所有經(jīng)線的長(zhǎng)度皆相等,故A正確;
所有經(jīng)線都相交于南北極點(diǎn),故B不符合題意;
所有的經(jīng)線圈和赤道都能平分地球,故C不符合題意;
60°緯度的長(zhǎng)度是0°緯線的一半,故D不符合題意。
故選A。
