But beneath the South Island, the westward-moving Pacific Plate is crashing into and subducting beneath the northwest-moving Australian Plate.

但是在南岛下方，向西移动的太平洋板块撞击并俯冲到向西北移动的澳大利亚板块下方。

Or maybe the carbon in diamonds came from organic stuff in subducting tectonic plates, like stuff on the ocean floors, but not coal.

二是这些碳来源于地壳俯冲板块中的有机物，像洋底中的某些东西，但不是煤。

For millions of years now, both the Rivera and Cocos plates have been subducting beneath the North American Plate here which is what's generated this continuous belt of volcanoes clear across the center of Mexico.

数百万年来，里韦拉板块和科科斯板块一直在北美板块下方俯冲，因此形成了横跨墨西哥中部的连续火山带。
