If that happens, slab pull could draw the oceanic crust under the continent, actually causing the Americas to move eastward toward Europe and the ocean floor to get smaller.

若果真如此，岩板拉力会将海洋地壳拖拽到大陆之下，实际上会使美洲大陆向东移动靠近欧洲，海床也会缩小。

The coupling relation between the directions of the overriding plate extension and oceanic plate motion supports the slab rollback model for the back-arc extension.

本次工作所发现的弧后大陆边缘伸展方向和大洋板块运动方向相吻合，支持弧后拉张机制应为板片后退模式。
