Outside the core there is a very deep and active convection zone, but that doesn't interact with the material in the core itself.

在地核之外有一个非常深的活跃的对流区，但它不与地核内部的物质相互作用。

Beyond that is the " convection zone" where rising and descending bubbles of plasma create an unstable regime (see diagram).

在那之外是“对流区”，等离子体的上升和下降气泡在其中产生不稳定的状态（见图）。

While the seismic waves generated by an earthquake usually come from a point source in the Earth's crust, the Sun's oscillations are triggered by countless disturbances occurring throughout its convection zone.

虽然地震产生的地震波通常来自地壳中的点源，但太阳的振荡是由其对流区发生的无数扰动引发的。
