In the same plate, the movement of the plate represented by the vector differs from place to place. why?

Yes,

Explanation:

As Vector is defined by magnitude and direction it when applied in the same plates or slabs of rock the movement is defined by the intensity rock-forming mineral as the slabs on the earth are moving in the direction with the plate tectonics from below. On the various places of the earth, the rocks show different bend and folds as an impact of slab push and pull on both opposing ends of the plates. As the risk entre to different phases within the earth geologic history. As in place that is near to the equator the rocks are older mass rearranged in shoreline and newer ones and located near to the magnetic rocks and near the plate ridges. Depending on the direction of displacement od the terrestrial rock they are detection is affected by the convective, divergent or transform boundary of plate motion.
