当海洋底部开始下沉到地幔中，它会同时将整个海底板块拖拽下去。
As the ocean floor plate begins to sink down into the mantle, it would drag or pull the entire plate along with it.
这样在海洋表面的碳酸盐的沉积物通过板块构造返回地球中。
This makes carbonate sediments on the floor of the ocean that are subducted back into the Earth though plate tectonics.
随着海洋的消失，金星可能再也不能进行板块重组了。

这种地槽的形成与造山作用的循环可以以一种简单和自然的方式与板块构造的海洋开合理论结合起来。
The cycle of geosyncline formation and orogeny can be integrated with the plate tectonics concept of opening and closing oceans in a simple and natural way.
海洋和陆地下面的岩石层或板块在缓慢地运动。
Separate rock layers, or plates, under the oceans and continents move very slowly.
板块运动理论的一个关键点就是在地质历史的尺度内，海洋盆地的开合是因为板块转换，具有转换特征。
A key aspect of plate tectonic theory is that on geologic time scales ocean basins are transient features, opening and closing as plates shift.
随着火山的成长变化，它们伸出海洋面，逐渐在仰冲板块的前沿形成一系列岛屿。
As these volcanoes grow, they rise above the ocean surface to form lines of islands along the leading edge of the overriding plate.
将中国海洋地震按板块构造理论划分为三个大的层次：（1）西太平洋岛弧-海沟强活动带；
According to the theory of plate tectonics, China's oceanic earthquakes can be divided into three major levels: (1)Western Pacific Ocean arc-trench strong mobile belt;
