D) Satellites track seafloor spreading. C) GPS receivers send signals to each other to see if the units are getting closer together. How can the orientation of transform faults provide information about the direction of plate motion? A) Transform faults are oriented perpendicular to the direction of plate motion. 1 What evidence can
