2:53 12 Question 6 ABG During the 1960s, geologists used seismometers to record information that suggested Earth's plates were in motion. The data recovered by the seismometers showed that earthquakes, volcanoes, and other geologic features tend to occur or be present A. around the centers of tectonic plates. B. on the edges of tectonic plates. C. in Earth's outer core. D. in Earth's inner core. © 2025 Renaissance Learning, Inc. All rights reserved. testing.illuminateed.com

The groundbreaking work of geologists in the 1960s, especially in seismology, laid the foundation for the theory of plate tectonics. They analyzed patterns of seismic activity and identified that most earthquakes and volcanic activities occurred along the boundaries of tectonic plates, giving rise to the concept of plate interaction. This led to a better understanding of how continental drift and ocean floor spreading reshaped our planet over millions of years. In the real world, this knowledge has critical implications for modern construction, urban planning, and disaster preparedness. Regions on the edges of tectonic plates, often termed "ring of fire," face increased risks of earthquakes and volcanic eruptions. As a result, building codes are adapted to enhance structural integrity, and early warning systems are implemented to help minimize damage and save lives during seismic events.
