During the first half of the 20th century, the theory of plate tectonics was developed. Evidence supporting this theory included Wegener's mapping of the supercontinent Pangaea, the US Navy's discovery of paleomagnetic reversals, and evidence of sea floor spreading.What is the MOST recent evidence supporting plate tectonics? A) GPS monitoring and satellite imagery of crustal movements B) mapping earthquake epicenters with seismic technology C) sending probes deep into Earth's interior D) radioactive dating of fossil evidence
