美洲板块

纳斯卡板块实际上是潜于构建安第斯山脉的南美洲板块之下。

The Nazca Plate is actually diving under the South American Plate building the Andes Mountains .

东太平洋火山活动区，主要与太平洋东面的小板块（胡安德富卡板块、科科斯、纳斯卡板块）向美洲板块的俯冲有关；

B ) East Pacific Area : most volcanism are correlated with some small plates ( Juan de Fuca , Nazca , Cocos ), east to the Pacific Plate , subducted beneath the American Plate ;

再次是很难看到这一规定适用于山脊在南大西洋，那里既没有非洲还是美洲板块下沉的一部分。

An alternative theory is that the sinking part of the plate , which is denser than the hotter surrounding mantle , pulls the rest of the plate after it .

正如我所说的，最近大西洋海底正在扩张，变得越来越宽，但一些研究人员猜测，最终在海洋板块和美洲大陆板块相遇之处，会形成一条俯冲带。

So , as I said , currently the Atlantic Ocean floor is spreading , getting wider , but some researchers speculate that eventually a subduction zone will occur where the oceanic plate meets the continental plate of the Americas .

由于北美洲毗邻的太平洋板块运动活跃，几十亿吨古老岩石拔地而起就像锡纸被挤皱起来一样

With the Pacific of North America plates alive , billions of tons of ancient rock rise up crumpling like tinfoil .
