【题目】人类对地球形状的认识,经历了漫长的过程。下列对地球形状认识过程排序正确的是( )

①地球卫星照片②太阳和月亮形状的启示③天圆地方④麦哲伦船队环球航行

A.①③④②B.③②④①C.②①④③D.④①③②

【答案】B

【解析】

人类对地球的认识经过了漫长的过程,从天圆地方天如斗笠,地如覆盘麦哲伦环球航行地球的卫星照片,随着科技的发展,人们对地球的形状已经有了一个明确的认识:地球并不是一个正球体,而是一个两极稍扁、赤道略鼓的不规则球体,地球的平均半径6371千米 ,最大周长约4万千米,表面积约5.1亿平方千米。

由于受观测条件和科学技术的限制,人类对地球的认识经过了漫长的过程,从天圆地方天如斗笠,地如覆盘麦哲伦环球航行地球的卫星照片,后来人们经过精密的测量,证实了地球是一个两极部位稍扁的不规则球体。故选:B
