Answer:
Question 1 answer
Plate tectonic began in 1915 when Alfred Wegener proposed his theory which was continental drift. Usually scientists use waves to study the difference of the layers of earth. They use seismic waves. seismic waves are generated by earthquakes or nuclear-test explosions.
Those 3 pieces would be the fit of the continents, paleoclimate indicators, and geologic features. The rock formations of eastern North America, Northwestern Africa and Western Europe were found later to have a common origin. They were found to overlap.
