Which of the following statements comparing rates of plate motion determined from seafloor magnetic anomalies and the global positioning system (GPS) is correct?

Question

Quizplus · Accepted Answer

Rates of plate motions determined from seafloor magnetic anomalies (which give us information over millions of years) are very similar to those determined from GPS measurements (which provide data over the past few decades). This consistency suggests that the movements of tectonic plates have been relatively stable over these different time scales.
