What is an example of a technology that support the idea of continental drift, thus leading to a change in scientific knowledge?

An example of a technology that helps support the idea of continental drift, thus leading to a change in scientific knowledge is a seismometer. Seismometers that were placed world-wide showed where earthquakes, volcanoes, and other geologic features were aligned. Seismometers are instruments that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
