【題目】人類對(duì)地球形狀的認(rèn)識(shí),經(jīng)歷了漫長(zhǎng)的過(guò)程。下列對(duì)地球形狀認(rèn)識(shí)過(guò)程排序正確的是( )

①地球衛(wèi)星照片②太陽(yáng)和月亮形狀的啟示③天圓地方④麥哲倫船隊(duì)環(huán)球航行

A.①③④②B.③②④①C.②①④③D.④①③②

【答案】B

【解析】

人類對(duì)地球的認(rèn)識(shí)經(jīng)過(guò)了漫長(zhǎng)的過(guò)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,隨著科技的發(fā)展,人們對(duì)地球的形狀已經(jīng)有了一個(gè)明確的認(rèn)識(shí):地球并不是一個(gè)正球體,而是一個(gè)兩極稍扁、赤道略鼓的不規(guī)則球體,地球的平均半徑6371千米 ,最大周長(zhǎng)約4萬(wàn)千米,表面積約5.1億平方千米。

由于受觀測(cè)條件和科學(xué)技術(shù)的限制,人類對(duì)地球的認(rèn)識(shí)經(jīng)過(guò)了漫長(zhǎng)的過(guò)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(lái)人們經(jīng)過(guò)精密的測(cè)量,證實(shí)了地球是一個(gè)兩極部位稍扁的不規(guī)則球體。故選:B
