【題目】人類認(rèn)識地球有一個(gè)漫長的歷史過程,下面現(xiàn)象能證明地球形狀的是( )

①日月都從天空東方升起,西方落下②1519-1522年,麥哲倫船隊(duì)環(huán)球航行成功③地球表面積為5.1億平方千米 ④月食現(xiàn)象

A.①②B.②③C.③④D.②④

【答案】D

【解析】

根據(jù),人類對地球的認(rèn)識經(jīng)過了漫長的過程,從天圓地方→天如斗笠,地如覆盤→麥哲倫環(huán)球航行→地球的衛(wèi)星照片,后來證實(shí)了地球是一個(gè)兩極部位稍扁的不規(guī)則球體進(jìn)行分析解答。

地球是兩極部位略扁、赤道略鼓的不規(guī)則的球體。能證明地球形狀的例子很多,如:麥哲倫船隊(duì)環(huán)球航行;月食尤其是月環(huán)食時(shí),可以看到地球擋在太陽和月球之間的影子,月食就是地球在月亮上的投影,從形狀可以證明地球是圓的;在外太空觀察以及地球的衛(wèi)星照片等等。故選:D
