地球的大陆一直在以肉眼观察不到的速度缓慢移动,运动的动力来源就是地球内部的地幔对流。地幔在地下的缓慢移动,带动了地表处的岩石也一起运动,每年移动的速度只有几厘米,但是经过上亿年的运动,就会使大陆漂移到数千千米的远方。这就是板块运动学说所描述的板块运动过程。板块 The continent of the earth has been slowly moving at a rate not visible to the naked eye. The source of the movement is the mantle convection inside the Earth. The slow movement of the mantle in the ground led the rocks along the surface to move together, moving only a few centimeters a year, but after millions of years of movement, the continent could drift to thousands of kilometers away. This is the plate movement described by plate kinematics. Plate
