tectonics

Geologists describe the motion of the plates and the consequences of such motion as plate tectonics .

地质学家把板块运动及这种运动所造成的后果看作是板块构造运动。

The job of plate tectonics is to unravel the clues in that snapshot to learn the dance steps to determine where the dancers have been and where they are going.

板块构造学的工作就是要揭示那快照的线索，了解它的舞步，确定舞蹈者曾去过和将要去哪里。
