摘要
地壳板块的形成,是由于外来星球的撞击而造成的。太平洋就是巨大的撞击坑,大西洋则是撞击产生的地球背面的S形裂谷。地球上的水,也很有可能主要来源于这次撞击。
The plates that make up the earth's crust are from a violent collision that happened between the earth and another planet from outer space. The Pacific Ocean is a giant hollow resulting from a collision and the Atlantic Ocean is a rift valley shaping like a huge “S”. The water on the earth is possibly mainly from this collislon.
