【题目】下列关于地球的叙述,正确的是(  )
A.人类对地球形状的认识经历了“浑天说”到“盖天说”到“地球是球体”的过程
B.地球是一个海洋面积占5.1亿平方千米的不规则球体
C.人类通过地球卫星照片认识了地球的真实形状
D.三分陆地,七分海洋是对地球海陆分布最精确的描述

【答案】C
【解析】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,从盖天说→浑天说→麦哲伦环球航行→地球的卫星照片,最后证实了地球是一个两极部位稍扁的不规则球体,故A错误。科学家经过长期的精密测量,发现地球是一个两极稍扁、赤道略鼓的不规则球体,面积约5。1亿平方千米,故B错误。地球是一个巨大的球体。今天,人们通过从宇宙空间发回的地球卫星照片,就能看清地球的真实形状,故C正确。人们常用“七分海洋,三分陆地”粗略地说明全球海洋和陆地面积的比例,故D错误。
故选:C。
