Chapter 20: The Earth Through Time

Chapter 20: The Earth Through Time. Introduction: Tracking Past Plate Motions (1). The evidence in support of plate motions comes from measurements made with the Global Positioning System (GPS). However, evidence of past plate motions is not obtained through GPS.

Seafloor Spreading

Seafloor Spreading. The plates pull apart and new crust is formed when magma goes to the surface and cools. Seafloor spreading shows evidence of polarity reversing. The older parts of crust are pushed into subduction zones causing earthquakes and mountains to push up.
