地幔，这种物质可以在板块边界处下沉，然后向上回流到较远的地方，再与地壳相碰撞——这个过程被称为小规模的对流。
Mantle material can sink at a plate boundary, and then flow back upward farther away, pushing on the crust - a process called small scale convection.
似乎有很多的小火山，以减轻下方，而不是仅仅在为地球上的板块边界地壳岩浆的压力。
It seems to have many small volcanoes to relieve the stress of the magma beneath the crust rather than just at the plate boundaries as on the Earth.
最深的地震通常发生在板块边界的地方的地壳正在俯冲到地球的地幔。
The deepest earthquakes typically occur at plate boundaries where the earth's crust is being subducted into the earth's mantle.
