These plates, some carrying continents, others the floors of ocean basins, 'float' on the semi--fluid asthenosphere below.

这些板块“漂”面的半体软圈上，有些板块承载大陆，其他板块则承载海洋盆地的底部。

The currents in the asthenosphere pull along the base of the lithosphere, moving the continents above.

软圈中的洋岩石圈底部拉动，将上方的大陆移动。

The tremendous heat at the center of the Earth, compared to the less deep layers, can set up convection currents in the asthenosphere.

与较浅的地层相比，地球中心的巨大热量可以软圈中形成对。
