英语语法分析

It would be odd if the rising convection currents kept exact pace with them.

如果上升的对流与它们保持保持完全一致，那就奇怪了。

Theoretically, this convection would carry the continental plates along as though they were on a conveyor belt.

从理论上讲，这种对流会把大陆板块带到一起，好像把它们放在传送带上一样。

Another possibility is that the sinking plate cools the neighboring mantle and produces convection currents that move the plates.

另一种可能是下沉的板块冷却了邻近的地幔，并产生对流，使板块移动。
