Of course, the Earth's plate tectonics and water are not the only things to set it apart.

当然，地球板块构造和水并不是唯一使它与众不同东西。

Tectonic plates are usually in contact with water for thousands of years and absorb some of it.

构造板块通常与水接触上千年并吸收其一部分。

Excluding fossils, McSween says, a quartz-rich sandstone is probably one of the most Earth-specific rocks imaginable—creating one would require plate tectonics, erosion, and water.

麦克斯温说，除去化石，富含石英砂岩可能是我们所能想象到最具地球特色岩石之一——要想形成砂岩，需要板块构造、侵蚀和水作用。

" Earth, with plate tectonics and water, has this easy way of making granite all the time, " says planetary scientist Matthew Siegler of the Planetary Science Institute in Tucson, Arizona, who helped spot the granite on the moon.

亚利桑那州图森市行星科学研究所行星科学家马修·西格勒帮助发现了月球上花岗岩，他说：“地球有板块构造和水，一直都很容易形成花岗岩。”
