【題目】下列現(xiàn)象,能說明地球是球體的是( )
①月食現(xiàn)象 ②日月星辰的東升西落 ③麥哲倫環(huán)球航 ④北極星指向北方 ⑤地球衛(wèi)星照片 ⑥海邊看船駛來,先見桅桿后見船身
A. ①③④⑥ B. ②③④⑥ C. ①③⑤⑥ D. ②④⑤⑥
【答案】C
【解析】
根據(jù)地球是球體的證據(jù),進行分析解答。人類對地球的認識經(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,后來證實了地球是一個兩極部位稍扁的不規(guī)則球體。
地球是兩極部位略扁的不規(guī)則的球體。能證明地球形狀的例子很多。月食尤其是月環(huán)食時,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,說明①是正確的;日、月都從天空東方升起,西方下落是地球自轉(zhuǎn)造成的,與球形無關(guān),故排除②。麥哲倫船隊的環(huán)球航行證實了地球是一個球體,故③正確。北極星指向北方,說明北極指向北極星附近,不能說明地球是一個球體,故排除④。地球的衛(wèi)星照片,可以看出地球是一個球體,故⑤正確;遠處駛來的帆船總是先看到桅桿,再看到船身,能證明地球是球形,故⑥正確。故選C。
