How have technologies such as sonar and global positioning system been used to provide evidence supporting the theory of plate techtonics?

Technologies like sonar and the Global Positioning System (GPS) have significantly advanced our understanding of plate tectonics. Sonar has been employed to map the ocean floor, revealing mid-ocean ridges and deep-sea trenches, which are key features of plate boundaries. Meanwhile, GPS technology allows for precise measurements of tectonic plate movements, showing how continents shift over time. Together, these tools have provided compelling evidence of the dynamic nature of Earth’s crust and the processes driving plate tectonics.
