题目内容

【题目】东西半球以哪一组经线圈划分( )

A. 东经90度西经90度 B. 东经20度西经160度

C. 西经20度东经160度 D. 东经40度西经140度

【答案】C

【解析】

东西半球分界线是20°W和160°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．南北半球的划分是以0°纬线即赤道为界，赤道以北为北半球，以南为南半球。

任何两条相对的经线（经度之和为180°），都组成一个经线圈；任何一个经线圈，都把地球分成相等的两个半球。东经180°和西经180°，实际上重合为一条经线，即180°经线。国际上习惯用20°W和160°E这两条经线组成的经线圈，作为划分东西半球的界线，因为这个经线圈基本上是从海洋通过，避免了以0°和180°经线划界，将欧洲和非洲的一些国家分隔在两个半球上。故选C。
