地球上到處都有戰壕，包括戰爭期間制造的人工戰壕，但是我們有太平洋上的馬里亞納海溝，很少有人潛入其中，而且只有詹姆斯·卡梅隆的幫助。馬里亞納海溝的深度是10994 m10.994公里，所以如果地球的大小是一個臺球，那么這個區域的深度就相當于320粒砂紙的深度球體沒有凹坑或凸起，但地球有，這也是它不太圓的另一個原因。—格雷戈里

There are trenches throughout Earth, including manmade trenches made during wars, yet we have the Mariana Trench in the Pacific, which few people dived in and 1 unassisted (James Cameron).The depth of the Mariana Trench is 10,994 m(10.994 km), so if Earth were the size of a billiard ball, that area would be like the depth on 320 grit sandpaper.A sphere doesn't have pits or bumps, but Earth does, and that's another reason it's not quite round. - Gregory
