Other mechanisms would be more likely to have taken place more gradually, over an extended period, or at different times on different continents.

其他机制更可能是较为循序渐进的，在更长时间段或在不同的大陆上的不同时间发生。

They therefore permit the reconstruction of the process of seafloor spreading, and consequently of the geography of continents and of ocean basins in the past.

因此，它们可以重现海底扩张的过程，以及大陆和大洋盆地过去的地理位置发展过程。

This view may be correct: it has the advantage that the currents are driven by temperature differences that themselves depend on the position of the continents.

这种观点可能是正确的：它的优点是洋流是由温差驱动的，而温差本身又取决于大陆的位置。

There are several hypotheses, including warming or cooling of Earth, changes in seasonal fluctuations or ocean currents, and changing positions of the continents.

It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it.

While previously the gap between the continents had allowed a free flow of water, now the isthmus presented a barrier that divided the Atlantic Ocean from the Pacific Ocean.

Stephen Jay Gould, for example, argues that continental drift theory was rejected because it did not explain how continents could move through an apparently solid oceanic floor.

例如，斯蒂芬·杰伊·古尔德认为，大陆漂移理论之所以被否决，是因为它没有解释大陆是如何穿过明显很坚固的海底的。

Once it was understood how these plates move, it was possible to determine past movements of Earth's continents and how these slow movements have reshaped Earth's features at different times.

一旦人们了解了这些板块是如何运动的，就有可能确定过去地球上大陆的运动，以及这些缓慢的运动如何在不同时期重塑了地球的特征。

A likely explanation for this involves the fact that intercontinental migrations require both a land bridge connecting the two continents and the suitable habitat both on and across that land bridge.

对此，有一种可能的解释是，洲际迁移既需要连接两个大陆的大陆桥，也需要大陆桥上和桥对面存在合适的栖息地。
