American Tectonic Plate的意思|示意

Just off its coast is the Nazca plate, which rests below the south-eastern Pacific Ocean and slides beneath the South American tectonic plate by some 9 centimetres a year.

智利的海岸线外是纳斯卡板块，它位于太平洋的东南方下面，以每年9厘米的距离向南美板块下俯冲。

Most of the time, the two tectonic plates are stuck together, and the North American plate is squeezed, much like a playing card held between the thumb and forefinger.

大部分时间，这两个地址板块卡在一起，北美板块被挤压，很像一个扑克牌夹在大拇指和食指之间。
